| R5220X series pwm step-down dc/dc converte r with switch function no.ea-121-070824 1 outline the R5220X series are cmos-based pwm step-down dc /dc converters with synchronous rectifier, low supply current and ldo mode. dc/dc converter of the R5220X consists of an oscillator, a pwm control circuit, a reference voltage unit, an error amplifier, a soft-start circuit, protection circui ts, a protection against miss operation under low voltage (uvlo), pwm-dc to dc converter / ldo alternative circui t, a chip enable circuit, and a driver transistor. a high efficiency step-down dc/dc converter can be easily comp osed of this ic with only a few kinds of external components, or an inductor and capacitors. ldo of the R5220X consists of a vortage reference unit, an error amplifier, resistors for voltage setting, output current limit circuit, a driver transistor, and so on. the out put voltage is fixed internally in the R5220X. the output voltage of the dc/dc converter and the ldo can be set independently. pwm step-down dc/dc converter / ldo alternative circuit is active with mode pin of the R5220X series. thus, when the load current is small, the operation can be sw itching into the ldo operation from pwm operation by the logic of mode pin and the consumption current of the ic itself will be small at light load current. as protection circuits, the current limit circuit which limits peak curren t of lx at each clock cycle, and the latch type protection circuit which works if the term of the over-current condition keeps on a certain time in pwm mode. latch-type protection circuit works to latch an internal driver with ke eping it disable. to release the protection, after disable this ic with a chip enable circuit, enable it again, or rest art this ic with power-on or make the supply voltage at uvlo detector threshold level or lower than uvlo. features ? supply current ................................................................ typ. 350 a (dc/dc), typ. 5 a (vr) ? standby current .............................................................. typ. 0.1 a ? built-in driver on resi stance ......................................... p-channel 0.5 ? , n-channel 0.5 ?

R5220X 7 operation of step-down dc/dc converter and output current the step-down dc/dc converter charges energy in the inductor when l x transistor is on, and discharges the energy from the inductor when l x transistor is off and controls with less energy loss, so that a lower output voltage than the input voltage is obtained. the operation will be explained with reference to the following diagrams: R5220X 8 output current and selection of external components when p-channel tr. of l x is on: (wherein, ripple current p-p value is described as i rp , on resistance of p-channel tr. and n-channel tr. of l x are respectively described as r onp and r onn , and the dc resistor of the inductor is described as r l .) v in = v out + (r onp + r l ) i out + l i rp / ton ...................................................................equation 2 when p-channel tr. of l x is "off"(n-channel tr. is "on"): l i rp / toff = r onn i out + v out + r l i out ..................................................................equation 3 put equation 3 to equation 2 and solve for on duty of p-channel transistor, ton/(toff + ton) = d on , d on = (v out ? r onn i out + r l i out ) / (v in + r onn i out ? r onp i out )............................equation 4 ripple current is as follows; i rp = (v in ? v out ? r onp i out ? r l i out ) d on / fosc / l ................................................equation 5 wherein, peak current that flows through l, and l x tr. is as follows; ilmax = i out + i rp / 2 ......................................................................................................equation 6 consider ilmax, condition of input and output and select external components. ? the above explanation is directed to the calculation in an ideal case in continuous mode. R5220X 9 timing chart 1) ic start-up the timing chart as shown in the next describes the operation starting the ic is enabled with ce. when the ce pin voltage becomes higher than the threshold voltage, t he ic?s operations starts. at first, only the voltage regulator (vr) starts. the threshold level of the ce pin is between ce ?h? input voltage and ce ?l? input voltage. after starting the operation, the output capacitor (c out ) is charged with the output current of the vr, and the output level becomes the set vr output voltage. at this mom ent, the output of lx is ?off?, (?hi-z?), the pin voltage, v lx = v out through the external inductor l. secondly, the mode pin voltage is higher than the threshold voltage, internal operation of dc/dc starts. the threshold level is between mode ?h? input voltage and mode ?l? input voltage. the soft-start circuit inside the dc/dc converter?s operation is as follows: (case 1) dc/dc output voltage < vr output voltage after the soft-start time, while the output voltage level is down from the vr output voltage to dc/dc output voltage, the circuit is waiting for the start of dc/dc operation. when the output voltage reaches so set dc/dc output voltage level, the actual dc/dc operation starts. (case 2) dc/dc output voltage> vr output voltage the soft-start circuit of dc/dc converter makes the voltage reference unit of the ic rise gradually and be constant. after the voltage reference unit reaches the constant level which the output voltage of dc/dc converter can balance becomes the output voltage of vr, the set output voltage of dc/dc converter may be realized. therefore, the soft-start time means the time range of starting to the time when the voltage reference unit reaches the constant level, and the soft-start time is different from turning on speed in some cases. the operation starting time depends on the ability of the power supply, the load current, the inductance value, the capacitance value, and the voltage difference between the set vr output and the set dc/dc output. if ce and mode are on at once, the same operation as above is happened except the vr start-up and soft-start operation start at the same time. if mode signal is forced earlier than ce signal, this ic is stand-by until ce signal comes. therefore when the ce signal is set, the ic operation starts as above. ? v out voltage rising speed at start-up with power supply is affected by the next conditions: 1.the turning on speed of v in voltage limited by the power supply to the ic and the input capacitor c in . 2.the output capacitor, c out value and load current. ? dc/dc operation starting time 1.if the vr output > = dc/dc output, the operation starting time of the dc/dc converter is approximately equal to the next formula. t dc/dc_act = t ss + (v out_vr ? v out_dc/dc + 15mv) c out / (load current at mode change + 1 a) t ss : soft-start time v out_vr : vr output voltage v out_dc/dc : dc/dc output voltage *1 a is the supply current of the ic itself for the output. 2.if the vr output < dc/dc output, the operation starting time is the soft-start time + starting operation time which depends on the power supply, the load current, and the external components.
