L6565D ST Transition-Mode PFC Controller | 8-SOIC | 10-22V Supply, 50-300kHz

Product Overview

The L6565D is a current-mode primary controller specifically designed for high-performance power factor correction (PFC) boost converters operating in transition mode (TM). Manufactured by STMicroelectronics, this device integrates advanced features to achieve near-unity power factor and low total harmonic distortion (THD) in AC-DC applications. Housed in a compact 8-SOIC package, the L6565D offers a wide supply voltage range (10V to 22V) and programmable switching frequency up to 300 kHz, making it suitable for medium-power PFC stages in industrial and consumer electronics.
