DP9126X - Non-Isolated Buck APFC Offline LED Power Switch

Description

DP9126X series are a highly integrated power switch with constant current (CC) control for LED lighting applications.

The IC utilizes QuasiResonant (QR) Buck topology with active PFC control for high PF, low THD, and high efficiency.

Features

  • Active PFC for High PF and Low THD.
  • PF>0.9 with Universal Input.
  • Built-in HV Startup and IC Power Supply Circuit.
  • Internal 500V Power MOSFET.
  • Quasi-Resonant for High Efficiency.
  • ±1% CC Regulation.
  • Very Low VDD Operation Current.
  • Excellent Line and Load Regulation.
  • LED Open/Short Protection.
  • Build in Protections:.
  • Output Over Voltage Protection (OVP).
  • Cycle-by-Cycle Current Limiting (OCP).
  • Leading Edge Blanking (LEB).
  • LED Open.
