Product Description

Product Description:
KP212LGA is a high-performance primary-side controller for offline flyback and quasi-resonant buck power supplies. It provides high-accuracy constant-current and constant-voltage regulation using multi-mode control, supports both flyback and buck topologies, and drives an external MOSFET. The device features ultra-low standby power, optimized dynamic response, and comprehensive protection functions, making it suitable for chargers, adapters, and LED lighting applications.
