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) Pin Floating Protection VDD UVLO Available with SOT89,TO-92 and SOT233L Package DP9122 is a highly integrated power switch with Quasi-Resonant Buck (QR-Buck) constant current (CC) control for LED lighting applications.
DP9122 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 transformer demagnetization circuit, which eliminates transformer auxiliary winding.
