KP2164DP is an offline flyback AC-DC power switch IC designed for low-power adapter and charger applications. It integrates a 650V high-voltage MOSFET and primary-side control circuitry to provide a compact solution for isolated power supply designs.
The device operates in DCM flyback mode and supports constant voltage (CV) and constant current (CC) regulation, allowing it to be used in charger and adapter applications without requiring secondary-side feedback components.
KP2164DP includes multiple protection features such as over-voltage protection, over-load protection, thermal shutdown, UVLO, and current limiting to improve system reliability and safety.
