Product Description

The KP1264SP is a high-performance Active
Power Factor Correction (APFC) Quasi-Resonant (QR) Buck LED Power Switch designed for offline constant-current LED lighting applications. It integrates a high-voltage startup circuit and an internal 600V power MOSFET, eliminating the need for an auxiliary winding and reducing external component count. The device provides high power factor (>0.9), low THD, high efficiency, and high-accuracy constant-current regulation, making it suitable for compact and cost-effective LED driver designs.
