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

Description

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.

Features

  • Proprietary Output OVP Protection.
  • Integrated with 500V MOSFET.
  • No Auxiliary Winding Needed.
  • Quasi-Resonant for High Efficiency.
  • Built-in Thermal Foldback.
  • Built-in Charging Circuit for Fast Start-Up.
  • ±4% CC Regulation.
  • Very Low VDD Operation Current.
  • Built-in AC Line CC Compensation.
  • Build in Protections:.
  • LED Short/Open Protection.
  • On-Chip Thermal Fold-back (OTP).
  • Cycle-by-Cycle Current Limiting.
  • Leading Edge Blanking (LEB).
