Product Description
  • Product Description:
  • KP4060LGA is a high-frequency, multi-mode, high-efficiency secondary-side synchronous rectification controller designed for flyback power supplies. It drives an external MOSFET to replace Schottky rectifier diodes, improving conversion efficiency. The controller supports DCM, QR, CCM, and ACF flyback topologies, integrates a high-voltage VDD supply that eliminates the need for an auxiliary winding, and provides intelligent turn-on/zero-current detection for reliable fast-charging and adapter applications.
