KP12760FWPA is a family of highly integrated Constant Current LED power switch. The IC utilizes Quasi-Resonant (QR) Buck topology with active PFC control for high PF, low THD, and high efficiency.KP12760FWPA integrates 650V power MOSFET, 600V FRD, 800V Rectifier Bridge and internal demagnetization detection circuit with high voltage startup, which eliminates auxiliary winding for power supply and demagnetization and simplifies the design and production cost of the system. Additionally, the system surge performance is also optimized in KP12760FWPA to pass 4kV surge level with minimum system cost.
