KP1051 Datasheet (Kiwi) - Non-isolated Quasi-Resonant Buck LED Power Switch

KP1051, Non-isolated Quasi-Resonant Buck LED Power Switch

KP1051 is a highly integrated power switch with Quasi-Resonant Buck (QR-Buck) constant current (CC) control for LED lighting applications.

KP1051 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
