The KP1402SGA is a high-performance secondary-side synchronous rectifier (SR) controller designed for flyback AC-DC power supplies. It supports both Discontinuous Conduction Mode (DCM) and Quasi-Resonant (QR) flyback topologies, replacing conventional Schottky rectifier diodes to improve overall power conversion efficiency and reduce thermal losses. The device integrates an HVCC (high-voltage VDD supply) circuit, eliminating the need for an auxiliary supply and simplifying the power supply design. It is widely used in high-efficiency LED drivers, adapters, chargers, and industrial power supplies
