The AP3781 is a high-performance, lead-free, green power supply controller suitable for battery chargers and adapters. It operates on primary-side regulation with PFM and AM modes, providing high efficiency and low audible noise. Integrated protections include Vcc overvoltage, output OVP and UVP, short circuit, cycle-by-cycle current limit, open loop, and external/internal OTP. Packaged in SO-8, it supports flyback topology in discontinuous conduction mode, eliminating the need for opto-couplers, and offers adjustable line and cable compensation, making it ideal for power tools, routers, set-top boxes, and smart devices.
