Product Description

Product Description:
KP1079AWPA is a highly integrated non-isolated quasi-resonant buck LED power switch designed for constant-current LED lighting applications. It integrates a 500V power MOSFET, a 600V ultra-fast recovery diode, an 800V rectifier bridge, and a high-voltage self-supply circuit, eliminating the need for a VDD capacitor. The device provides high-efficiency operation, ±5% constant-current accuracy, and comprehensive protection features for reliable LED lighting designs.
