General Description

DP9127V is a highly integrated power switch with Quasi-Resonant Buck (QR-Buck) constant current (CC) control for LED lighting applications.

DP9127V combines a 500V power MOSFET switch with a power controller in one chip.

The IC also integrates high voltage startup/IC supply circuit and a novel transformer demagnetization circuit
