APW7075 Step-Up Converter and LDO Combo Features * * * * Built-In a 500mA LDO and Synchronous Step-Up DC-DC Converter Built-In PWM/PFM Operating Mode Provided Dual Input Power Sources Connect FB to OUT for 3.3V Output Voltage or GND for 2.5V Output Voltage or an External Resistor Divider for Adjustable Output Voltage. General Description The APW7075 is a PWM/PFM, high-efficiency and step-up DC-DC converter with an integrated LDO input switch for dual mode application. During battery mode operation, the APW7075 acts as synchronous rectifier and step-up DC-DC converter with a fixed or adjustable output voltage. When the VIN pin sense 5V input voltage, the APW7075 is switched to LDO operation mode, maintaining the constant output voltage. The input voltage ranges from 0.6 V to 4.5V for stepup DC-DC converter. The start-up is guaranteed at1V and the device is operating down to 0.6V. When the device is at LDO operating mode, the suitable output voltage 3.3V and loading current 500mA for maximum power consumption are guaranteed. The APW7075 is suited for dual mode and portable battery powered appliance with low-battery detector. In dual-mode applications, the APW7075 draws power from any available 5V USB connection and reverts to battery power when the USB power is removed. * * * * * * * * * * Fixed 300KHz Operating Frequency High Efficiency Up to 94% at 200mA Output Current 0.6V to 4.5V Operating Voltage 1V Start Up Input Voltage Low Battery Voltage Detection Reverse Voltage Protection Internal Synchronous Rectifier Automatic Detection Input Voltage Compact SOP-8-P and TSSOP-8 Packages Lead Free Available (RoHS Compliant) Applications * * * * * Dual Mode Power System USB Peripheral Camcorders and Digital Camera Hand-held Instrument PDAs Pin Description TSSOP-8 Top View VIN FB SHDN LBI SOP-8-P Top View VIN FB SHDN LBI 1 2 3 4 8 7 6 5 OUT LX GND LBO 1 2 3 4 8 7 6 5 OUT LX GND LBO = Thermal Pad (connected to GND plane for better heat dissipation) ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise customers to obtain the latest version of relevant information to verify before placing orders.

Rev. A.5 - Aug., 2005 15 www.anpec.com.tw APW7075 Function Description PFM Control Scheme The APW7075 features the PFM control scheme to improve the efficiency during light load. In PFM mode, the inductor stores the energy during internal N-channel MOSFET turns on, and the energy is transferred to output capacitors and load during internal P-channel MOSFET turns on. If the energy which is charged to output capacitors exceeds the requirement of load, the current will reverse from output capacitors to inductor and input capacitors. The PFM comparator compares the source (OUT) and drain (LX) of the internal P-channel MOSFET. When the current that flows through the internal P-channel MOSFET is backward (from OUT to LX), the internal P-channel MOSFET will be turned off, and the output capacitor supplies the load and maintains the output voltage. During PFM mode, the IC switches only as need to serve the load, reducing the switching frequency and associated losses in the internal switches and the external inductor. Some jitter is normal during transition from PFM to PWM mode; the transition of the PFM to PWM is dependent on the inductance values, VIN, and VOUT. The output ripple is higher during PFM operation, a larger output capacitor can be used to minimize the output ripple. Synchronous Rectification The APW7075 has an internal N-channel and a P-channel MOSFET, it is no need for external components, the internal low RDS(ON) P-channel MOSFET replaces the discrete Schottky diode, and it is reducing cost and board space. During the cycle off time, the P-channel MOSFET turns on, and the power Copyright (c) ANPEC Electronics Corp. Rev. A.5 - Aug., 2005 16 dissipation on the P-channel MOSFET is lower than discrete Schottky diode, thus the conversion efficiency can be improved. Shutdown The APW7075 has an active high enable function. Force SHDN high (>1.4V) to enable the step-up converter, SHDN low (<0.3V) to disable the step-up converter and the device enters shutdown mode. In shutdown mode, the converter stops switching and all internal control circuits are turned off, but the output is still applied by input voltage through the body diode of Pchannel MOSFET, it is about Vin-0.6V. Note that when the output is applied from the VIN (LDO mode), the shutdown function is disabled. Soft Start The APW7075 provides the soft-start function to get the controlled output voltage rise. When battery voltage (<1.8V) is supplied to the device and exceeds the start-up voltage, the internal N-channel and P-channel MOSFETs start to switch and pump up the output voltage to 1.8V( if the battery voltage is over 1.8V, the output voltage will equal battery voltage during this time ), which control circuitry can operate normally . The soft start controls the rise of internal reference voltage, when the internal reference voltage exceeds the feedback voltage which is divided by the resistor from output voltage, the soft-start circuit will control the output voltage until the output voltage is in regulation. The soft-start interval is approximately 30ms. www.anpec.com.tw APW7075 Function Description (Cont.) LDO The output voltage has two operation modes. When VIN exceeds 3.9V, the output will become the LDO regulator and the step-up converter will be disabled. The LDO output is a P-channel low dropout regulator with 1A current limit. When the VIN is below 3.8V, the output will return to the step-up converter, and the LDO mode will be disabled. Note that when LDO mode is used, the output voltage should be under 3.8V Low Battery Detection The low battery detection is used to monitor the battery voltage and to generate a signal. This function includes two pins, LBI is the inverting input of the comparator and LBO is an open drain output (see block diagram). When the LBI voltage drops below the threshold voltage 0.6V, the open drain device will turn on and LBO becomes low. The Low battery threshold voltage can be programmed with a resistive divider from battery to LBI pin to ground. Since the LBO is an open drain output, it usually requires an external pull-up resistor. Inductor Selection The APW7075 works well with a 22uH inductor in most applications. The inductance values determine the inductor ripple current and affect the output current. Higher inductance values reduce ripple and improve efficiency. Lower inductance values have fast response but increase the ripple and reduce the efficiency. The maximum allowed LX current is 1A (the maximun. output current shows in Typical Characteristics) and so the peak inductor current cannot exceed it. The following equations calculate the inductor current, and The output voltage of APW7075 can be adjusted by an external resistor divider, or connect FB pin to OUT for 3.3V and to ground for 2.5V (see Application Schematic). The internal reference voltage is 1.2V and the allowed output voltage is from 2.5V to 5.5V. The following equation can be used to calculate the output voltage: Copyright (c) ANPEC Electronics Corp. Rev. A.5 - Aug., 2005 17 VOUT = 1 + R1 R2 x 1.2V Programming Low Battery Threshold Voltage The low battery threshold voltage can be programmed with a resistive divider from battery to LBI pin to ground (see Application Schematic). The internal reference voltage is 0.6V, and the low battery threshold voltage must be below the battery voltage. The following equation can be used to calculate the low battery threshold voltage: VBAT - TH = 1 + R3 R4 x 0.6V Application Information Output Voltage Selection output current. IOUT = IL x (1-D) IL = (VOUT- VIN) x Where: D= (1- D) Lx f VOUT -VIN VOUT www.anpec.com.tw APW7075 Function Description (Cont.) Inductor Selection (Cont.) The inductor' DC resistance affects the efficiency; s larger resistance dissipates more power, it should be as small as possible. It is important to choose the inductor' saturation current rating greater than the s peak current which the inductor will flow in the application. Boost Converter Input Capacitor Selection At least a 10uF input capacitor is recommended to stabilize the battery voltage and minimize the peak current ripple from the battery. LDO Input Capacitor Selection The LDO input capacitor with larger values and lower ESRs provide better PSRR and line transient response. At least a 10uF capacitor is recommended. USB 5V C3 10uF C4 1uF C2 100uF Layout Considerations The correct PCB layout is important for all switching converters. If the layout is not carefully done, the regulator could show stability problems as well as EMI problems. Figure. 5 illustrates the layout guidelines, the bold lines indicate the high current paths; these traces must be short and wide. The input capacitors, output capacitors, and the inductor should be as close to the IC as possible. Use a common ground plane for power ground and a different one for control ground to minimize the effects of ground noise. Connect these ground planes at a node close to the GND pin of IC. The feedback and LBI resistor dividers should be placed as close to the IC as possible. Output Capacitor Selection The output capacitor is used for supplying the output during internal N-channel MOSFET turns on time. Larger capacitance and lower ESR reduce the output voltage ripple. The output voltage supplies the power to the IC and so the output voltage ripple must be as small as possible to provide better PSRR. In general, a 100uF to 220uF low ESR Tantalum capacitor is recommended, a 1uF ceramic capacitor in parallel for bypassing the noise is also recommended. The following equation calculates the output ripple. Voripple= IOUTx ( VOUT - VBAT + ESR) COUTxFSW x VOUT 1 2 3 4 VIN FB SHDN LBI OUT LX GND LBO 8 7 6 5 VOUT C1 10uF 22UH VBAT APW7075 Figure 5.
