STMicroelectronics L6563S Enhanced Transition-Mode PFC Controller Datasheet
The L6563S is a current-mode Power Factor Correction (PFC) controller operating in transition mode (TM). It features a highly linear multiplier and a special correction circuit to reduce crossover distortion, enabling wide-range mains operation with extremely low Total Harmonic Distortion (THD) over a large load range. The device includes an accurate internal voltage reference (1% @ 25°C) and a voltage feedforward function to optimize loop stability and improve line transient response.

What is the main advantage of FOT control over fixed-frequency PWM?
FOT control couples the simplicity and affordability of transition mode operation with the high-current capability of continuous conduction mode operation.
Does FOT control require a specialized control IC?
No, it does not need a specialized control IC, only a simple modification of a standard TM PFC controller with a few additional passive parts.
What is the rated output power of the demonstration board?
The demonstration board has a rated output power of 400 W.
From: AN2994 400 W FOT-controlled PFC Pre-regulator with L6563S Application Note
Can the board deliver more than its rated power with airflow?
Yes, with appropriate airflow and without circuit changes, it can easily deliver up to 450 W.
