DP9100 - Non-Isolated Buck APFC Offline LED Controller

General Description

DP9100 is a highly integrated LED Controller with constant current (CC) control for LED lighting applications.

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

Key Features

  • Active PFC for High PF and Low THD.
  • PF>0.9 with Universal Input.
  • Built-in HV Startup and IC Power Supply Circuit.
  • 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/Short Protection.
  • On-Chip T.
