Gnd Vaux TEA1501 Bt Ref 3 4 MGM821 6 5 1998 Aug 19 4 Philips Semiconductors Preliminary specification Greeny; GreenChipTM FUNCTIONAL DESCRIPTION The TEA1501 contains a high voltage power switch, a high voltage startup circuit and low voltage control circuitry on the same IC. Together with a transformer and a few external components a low power, isolated, flyback converter can be built. The Greeny system operates in a burst mode. During each burst period the output voltage is regulated to a desired voltage level. System operation ON/OFF The Greeny system can be switched on and off by means of a low cost, low voltage switch. In the Off mode the startup current source and power switch are disabled. In the On mode, Greeny delivers the startup current for the supply capacitor and after the supply voltage reaches the startup level Greeny activates the power switch. STARTUP The startup is realized with a high voltage startup current source instead of a dissipative bleeder resistor which is commonly used by low voltage control ICs. When Greeny is switched on, the startup current source is enabled and starts charging the Vaux capacitor. The startup current level is high and accurate (typical 1.8 mA) which results in a well-defined and short startup time, within 0.25 s. After the supply voltage reaches the startup level the current source is switched off and the Vaux capacitor supplies the chip. Reducing the power dissipation in the current source to zero after startup is one of the green features of Greeny. OPERATION After startup the flyback converter starts delivering energy to the secondary and auxiliary winding. The Greeny system works with fixed switching frequency and fixed peak current. TEA1501 As all the windings of the flyback transformer have the same flux variation, the secondary voltage and the auxiliary voltage are related via the turns-ratio (ns/na). Therefore, the isolated secondary voltage is controlled by the non-isolated auxiliary voltage. The burst mode operates by switching at high frequency until the Vaux voltage reaches its regulation level of 20 V. Greeny stops switching until the time period set by the burst oscillator has expired. At the start of the next burst period Greeny starts switching at high frequency and repeats the cycle again. To guarantee a stable operation in a burst mode controlled system a Vaux slope compensation circuit is integrated in Greeny. The Greeny system delivers a constant voltage to the secondary load until a burst duty cycle of 40%. DATA TRANSFER The TEA1501 has a data transfer function which makes communication from the isolated secondary side to the non-isolated primary side of the transformer possible, without using an opto-coupler. This communication function is activated by increasing the secondary load. With this data transfer function a main power supply can be switched on and off by the Greeny system. The power delivered to the secondary and auxiliary winding is proportional to the number of primary current pulses per burst period, provided that the converter operates in discontinuous conduction mode. During each burst period the number of primary current pulses is counted. A threshold (Ndata) of 56 pulses is integrated. The clamp level on the OOD pin is set to data-on level from data-off level in case the Ndata threshold is passed. This data-on clamp level can be sensed by the on/off input of a main supply control IC of the GreenChipTM family. The data-on clamp level is maintained until a burst appears with a number of pulses below the Ndata threshold. 1998 Aug 19 5 Philips Semiconductors Preliminary specification Greeny; GreenChipTM Waveforms of Greeny in the Off mode, Startup mode and Operation mode TEA1501 handbook, full pagewidth VDrn detection level VSrc regulation level VVaux Vout VBt VOOD on/off level switch period switch on time off startup operation burst on time burst period MGM828 Fig.4 Waveforms of Greeny in the Off mode, Startup mode and Operation mode. 1998 Aug 19 6 Philips Semiconductors Preliminary specification Greeny; GreenChipTM CIRCUIT BLOCK DESCRIPTION On/Off/Data section The On/Off/Data block contains a comparator for the on/off level and is active if the drain voltage is above 50 V (DC). The typical current consumption in Off mode is 40 A. The data signal changes the clamp level on the OOD pin to indicate data transfer: low clamp level for data-off and high clamp level for data-on. Vaux management The Vaux management block is active when Greeny is in the On mode. This Vaux management block senses the Vaux voltage and determines the state of Greeny: startup or normal operation. During startup the following circuits are active: On/Off/Data section, Reference block (partial), Vaux management, Temperature protection and the Startup current source. Startup current source TEA1501 The startup sequence is carried out using an accurate startup current source. The startup current flows from the Drn pin to the Vaux pin via the startup current source and charges the Vaux capacitor. When Vaux reaches the startup threshold the startup current is switched off and the flyback converter starts operating and the output voltage rises. The Vaux capacitor must be capable of supplying the entire supply current (IVaux(LOW)) until the output voltage is in regulation. From that moment the Vaux capacitor is charged by the flyback converter via the auxiliary winding. Reference block The reference block contains a bandgap circuit which determines all the accurate and temperature independent reference voltages and currents. It defines the voltage detection level for the primary current comparator and it defines the voltage at the Ref pin. The value of the reference resistor determines the burst frequency, the switching frequency and the leading edge blanking time. Temperature protection The temperature protection circuit senses the chip temperature using a proportional to absolute temperature voltage (Vptat) generated in the reference block. If the chip temperature exceeds 140 C the power switch and the startup current source are disabled. When the chip cools down below 100 C, the startup circuit is enabled again. Switch oscillator handbook, halfpage operation IVaux 12 V UVLO 16 V Vstart 20 V VVaux(max) VVaux Istart startup MGM824 Fig.5 IVaux versus VVaux. The switch oscillator determines the switching frequency and the maximum on-time of the power switch. The maximum on-time is set at 66% of the switching period. The switching frequency is determined by the reference resistor at the Ref pin and an internal capacitor. The switching frequency can be adjusted in a range from 20 to 50 kHz, thus above the audible spectrum. 1998 Aug 19 7 Philips Semiconductors Preliminary specification Greeny; GreenChipTM Burst oscillator The burst oscillator generates a triangular wave signal for determination of the burst frequency. The burst frequency is determined accurately and temperature independent by the externally connected reference resistor RRef and burst capacitor CBt. Gate driver The gate driver switches the power switch. The power switch is turned on at the beginning of every oscillator cycle and is turned off by the primary current comparator or by the maximum on-time. The power switch is also prevented from turning on if the Vaux voltage has reached its regulation level or in case of active over temperature protection or in case of active under voltage lockout protection. Power switch The power switch is an integrated high voltage LDMOST with a Rdson of 40 , a maximum peak drain voltage of 650 V, a maximum continuous drain voltage of 500 V and a maximum drain current of 0.25 A. Primary current comparator The primary current comparator senses the voltage across the external sense resistor RSrc which reflects the primary current. The detection level of the comparator is 0.5 V. The power switch is switched off quickly when the source voltage exceeds this detection level. The comparator has a typical propagation delay of 80 ns. If the dV/dt of the drain voltage has to be limited for EMI reasons, a capacitor can be connected between the Drn and Src pins of Greeny. The discharge current of this EMI capacitor does not flow through the sense resistor RSrc and does not activate the comparator. Leading edge blanking To prevent the power switch from switching off due to the discharge current of the capacitance on the Drn pin a Leading Edge Blanking (LEB) circuit has been implemented. The leading edge blanking time is defined as the maximum duration time needed to discharge the capacitance at the drain of the power switch. The leading edge blanking time is determined by the reference resistor to obtain an accurate and temperature independent time. The LEB time tracks with the period time of the switch oscillator. 2 1 P load = x -- x L p x I prim x f burst x N 2 TEA1501 Modulator The modulator determines the regulation level of the Vaux voltage. For a burst duty cycle from 0 to 40% the Vaux voltage is regulated to 20 V. For stable operation in burst mode a decrease in regulation voltage is integrated for a burst duty cycle above 40%. At 100% burst duty cycle the regulation voltage is 17.5 V. handbook, halfpage regulation MGM826 level Vaux (V) 20 17.5 SVaux 0 CPVaux 0 40 burst duty cycle (%) 100 Fig.6 Regulation level VVaux versus burst duty cycle. Counter The power delivered to the load (auxiliary and secondary) is a function of the number of energy pulses per burst, according to the following formula: Where is the efficiency, Lp is the primary inductance, Iprim is the primary peak current, fburst is the burst frequency and N is the number of pulses in one burst period. The counter counts the number of pulses in each burst period and detects if the Ndata threshold is passed. The counter state is used for the data transfer function and for the supply current tracking. 1998 Aug 19 8 Philips Semiconductors Preliminary specification Greeny; GreenChipTM Supply current tracking For obtaining good load regulation, especially with low cost transformers, a tracking circuit is included. The tracking circuit makes the supply current of Greeny a function of the secondary load. This makes the voltage drop across the series resistance of the auxiliary winding proportional to the voltage drop across the series resistance of the secondary winding. Therefore, the secondary output voltage tracks with the Vaux regulation voltage. The tracking starts at a counter state of 28. For a counter state from 28 up to 112 (typical values) the supply current of Greeny rises linearly with the counter state according to the following formula (see Fig.7). I Vaux = k tracking x N For counter states of 112 and higher the supply current remains on its maximum value.

Switch oscillator The maximum output power of the converter is a function of the switching frequency, provided that the converter operates in discontinuous conduction mode. P out(max) 2 1 = x -- x L p x I prim x f switch 2 TEA1501 Burst oscillator The power threshold for data transfer is determined by the burst frequency, according to the following formula: 2 1 P data = x -- x L p x I prim x f burst x N data 2 The power ratio between Pdata and Pout(max) is therefore: f burst x N data P data --------------------- = -----------------------------f switch P out(max) The desired Pdata/Pout(max) ratio determines the burst frequency. For example, when the desired Pdata/Pout(max) ratio is 0.5 then the burst frequency has to be 450 Hz at 50 kHz switching frequency. The burst frequency can be adjusted by the reference resistor RRef and the burst capacitor CBt as shown below: 1 f burst = --------------------------------------------k burst x R Ref x C Bt MINIMUM VALUE OF CBt The minimum value for capacitor CBt is 3.3 nF. Where is the efficiency, Lp is the primary inductance, Iprim is the primary peak current and fswitch is the switching frequency. The switching frequency can be adjusted between 20 and 50 kHz by the reference resistor RRef: 1 f switch = -------------------------------k switch x R Ref RANGE OF RRef VALUES The minimum value for resistor RRef is 24 k, the maximum value is 62 k. Leading edge blanking The leading edge blanking time is determined by the reference resistor RRef as shown below: t LEB = t constant + ( k LEB x R Ref ) The leading edge blanking time consists of a constant time and a time which tracks with the period time of the switch oscillator handbook, halfpage MGM827 900 fburst (Hz) fswitch = 50 kHz 450 fswitch = 20 kHz 180 0 0 0.5 1 Pdata/Pout(max) Fig.8 fburst versus Pdata/Pout(max). 1998 Aug 19 10 Philips Semiconductors Preliminary specification Greeny; GreenChipTM TEA1501 LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134).

Together with a GreenChipTM TEA1504 a power supply with ultra low standby power can be built where Greeny supplies the microprocessor with the power on/off indicator and the GreenChipTM controls the main power supply during normal operation. Operation modes The power supply with a Greeny TEA1501 and a GreenChipTM TEA1504 can be in three different modes, according to the state of switches S1 and S2 (see Fig.9). Table 1 S1 Open Operation modes of power supply S2 Open or Closed Open OPERATION MODE Greeny is in Off mode, GreenChipTM is in Off mode, Power supply is in Off mode. Greeny is On mode, GreenChipTM is in Off mode, Power supply is in Standby mode. Greeny is in On mode, GreenChipTM is in On mode, Power supply is in Normal operation mode. TEA1501 When the switch S1 is opened the voltages on the OOD pin of Greeny and the OOB pin of the GreenChipTM are 0 V. The power supply and the power on/off indicator (LED) are switched off immediately and the power supply is in the Off mode again. Power supply in Standby mode When switch S1 is closed Greeny is in the On mode and supplies the microprocessor and the power on/off indicator. The microprocessor controls the state of switch S2. The power supply is in the Standby mode when switch S2 is open. The output power of Greeny is determined by the microprocessor and is below the Pdata level when switch S2 is open. The clamp level on the OOD pin of Greeny is the data-off level with a typical value of 1.3 V which is below the on/off level of the GreenChipTM which has a typical value of 2.5 V. The GreenChipTM remains in Off mode. Power supply in Normal operation mode The power supply changes its operation mode from Standby to Normal operation by closing the switch S2. The switch S2 is placed at the isolated secondary side of the Greeny and controls, via the data transfer function of Greeny, the operation mode of the power supply. When the microprocessor closes switch S2 the output power of Greeny is increased. The output power exceeds the Pdata level and the clamp level on the OOD pin of Greeny is set to data-on level with a value of 4 V. The voltage on the OOB pin of the GreenChipTM is above its on/off level of 2.5 V and the GreenChipTM starts up. The power supply enters Normal operation mode, Greeny supplies the microprocessor and the GreenChipTM supplies the main load. Closed Closed Closed Power supply in Off mode The power supply can be switched on and off by means of the functional switch S1. This functional switch replaces the generally used high voltage mains switch. The power supply is in Off mode if the switch S1 is open. If the switch S1 is closed the voltage applied on the OOD pin of Greeny is above the on/off level (0.7 V) and Greeny starts up, the power supply enters the Standby mode or the Normal operation mode. 1998 Aug 19 14 Philips Semiconductors Preliminary specification Greeny; GreenChipTM APPLICATION DIAGRAM WITH GREENY TEA1501 AND GREENCHIPTM TEA1504 TEA1501 handbook, full pagewidth (1) S1 GreenChipTM output OOB Dem n.c.

Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (order code 9398 652 90011). Soldering by dipping or by wave The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. Repairing soldered joints Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 C, contact may be up to 5 seconds.
