act4524 rev 1.1, 22 - feb - 16 innovative power tm - 6 - www.active - semi.com copyright ? 2015 active - semi, inc. functional description clk mode there are three clock modes that depend on the mode pin configuration. during power up, device checks mode pin condition (floating, 82k resistor to ground or grounded) to decide which mode (native, master or slave) device should operate in. if only single act4524 is required, mode pin can be left float, and act4524 runs at native mode using internal oscillator clock. for high load current application (>3.5a), it's possible to use two act4524 to operate in parallel with one device as master to provide clock for the other (slave). two devices operate on the same frequency, but in opposite phase to optimize supply loading and emi performance.
act4524 rev 1.1, 22 - feb - 16 innovative power tm - 7 - www.active - semi.com copyright ? 2015 active - semi, inc. applications informa tion inductor selection the inductor maintains a continuous current to the output load. this inductor current has a ripple which is determined by the inductance value. higher inductance reduces the peak - to - peak ripple current. the trade off for high inductance value is the increase in inductor core size and series resistance, and the reduction in current handling capability. in general, select an inductance value l based on ripple current requirement: where v in is the input voltage, v out is the output voltage, f sw is the switching frequency, i loadmax is the maximum load current, and k ripple is the ripple factor. typically, choose k ripple = 30% to correspond to the peak - to - peak ripple current being 30% of the maximum load current. with a selected inductor value the peak - to - peak inductor current is estimated as: the peak inductor current is estimated as: the selected inductor should not saturate at i lpk. the maximum output current is calculated as: l lim is the internal current limit. external high voltage bias diode it is recommended that an external high voltage bias diode be added when the system has a 5v fixed input or the power supply generates a 5v output. this helps improve the efficiency of the regulator. the high voltage bias diode can be a low cost one such as in4148 or bat54. input capacitor the input capacitor needs to be carefully selected to maintain sufficiently low ripple at the supply input of the converter. a low esr capacitor is highly recommended. since large current flows in and out of this capacitor during switching, its esr also affects efficiency. the input capacitance needs to be higher than 10f. the best choice is the ceramic type, however, low esr tantalum or electrolytic types may also be used provided that the rms ripple current rating is higher than 50% of the output current. the input capacitor should be placed close to the vin and gnd pins of the ic, with the shortest traces as possible. in the case of tantalum or electrolytic types, they can be placed a little bit away of ic if a paralleled ceramic capacitor is placed right next to the ic. output capacitor the output capacitor also needs to have low esr to keep low output voltage ripple. the output ripple voltage is: where i outmax is the maximum output current, k ripple is the ripple factor, r esr is the esr of the output capacitor, f sw is the switching frequency, l is the inductance, and c out is the output capacitance. in the case of ceramic output capacitors, r esr is very small and only contributes a very small portion of the ripple. therefore, a lower capacitance value can be used for ceramic type. in the case of tantalum or electrolytic capacitors, the ripple is dominated by r esr multiplied by the ripple current. in that case, the output capacitor should be chosen to have sufficiently low esr. for ceramic type output capacitor, typically choose a capacitance of about 22f. for tantalum or electrolytic capacitors, choose a capacitor with less than 50m esr. a 330f or 470f electrolytic capacitor is recommended. rectifier diode use a low forward voltage drop (vf<0.5v) schottky diode as the rectifier to conduct current when the high - side power switch is off. the schottky diode must have current rating higher than the maximum output current and a reverse voltage rating higher than the maximum input voltage.
