DP9130B Datasheet (DP) - Non-isolated Quasi-Resonant Buck LED Power Switch

DP9130B, Non-isolated Quasi-Resonant Buck LED Power Switch

DP9130B is a highly integrated power switch with Quasi-Resonant Buck (QR-Buck) constant current (CC) control for LED lighting applications.

The IC has built in output Over Voltage Protection (OVP).

DP9130B combines a 500V power MOSFET switch with a power controller in one chip.

The IC also integr
