DP9127 - Non-isolated Quasi-Resonant Buck LED Power Switch
DP9127 is a highly integrated power switch with Quasi-Resonant Buck (QR-Buck) constant current (CC) control for LED lighting applications.
DP9127 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 transfo
