General Description

The AP3703 is a high performance AC/DC power sup-

ply controller for battery charger and adapter applica-

tions. The device uses Pulse Frequency Modulation

(PFM) method to build discontinuous conduction

mode (DCM) flyback power supplies.

The AP3703 provides accurate constant voltage, con-

stant current (CV/CC) regulation while removing the

opto-coupler and secondary control circuitry. It also

eliminates the need of loop compensation circuitry

while maintaining stability. The AP3703 achieves

excellent regulation and high average efficiency, yet

meets the requirement for no-load consumption less

than 100mW.

The AP3703 is available in SOT-23-5 package.
