General Description
The AP3766 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 conductionmode (DCM) flyback power supplies.
The AP3766 provides accurate constant voltage, con-stant current (CV/CC) regulation while removing theopto-coupler and secondary control circuitry. It alsoeliminates the need of loop compensation circuitrywhile maintaining stability. The AP3766 achievesexcellent regulation and high average efficiency, yetmeets the requirement for no-load consumption lessthan 30mW.
The AP3766 is available in SOT-23-6 package.
