Product Description
  • Product Description:
  • KP1073LSPA is a highly integrated non-isolated buck LED constant current power switch operating in quasi-resonant mode for high efficiency. It integrates a 500V high-voltage MOSFET and a high-voltage self-supply circuit, eliminating the need for an auxiliary winding and VDD capacitor. The device provides ±5% constant-current accuracy, excellent line and load regulation, ultra-low operating current, and comprehensive protection features for reliable offline LED lighting applications.
