DP9128V Datasheet (DP) - Non-isolated Quasi-Resonant Buck LED Power Switch

DP9128V, Non-isolated Quasi-Resonant Buck LED Power Switch

DP9128V is a highly integrated power switch with Quasi-Resonant Buck (QR-Buck) constant current (CC) control for LED lighting applications.

DP9128V 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 trans
