About this manual

The L6563H is a current-mode Power Factor Correction (PFC) controller operating in transition mode (TM). It integrates an on-board 700V start-up source and features a tracking boost function to adjust the output voltage based on the mains input. The device includes a fast bidirectional input voltage feedforward (1/V² correction) to improve line transient response and reduce Total Harmonic Distortion (THD).
