Product Description
  • Product Description:
  • KP1272FNQSPA is a high-power-factor quasi-resonant buck LED constant current driver designed for non-isolated offline LED lighting applications. It integrates a high-voltage MOSFET and a high-voltage supply circuit, eliminating the need for an external VDD capacitor. The device provides high efficiency, PF greater than 0.9, low harmonic distortion, accurate constant-current regulation, and comprehensive protection features for reliable LED driver designs.
