STMicroelectronics L6563H High Voltage Start-up Transition-mode PFC Controller Datasheet
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).

What is the main function of the SRK2000 in this design?
The SRK2000 is an SR driver dedicated to LLC resonant topology that controls the SR MOSFETs on the secondary side.
How does the design achieve low standby consumption?
Low standby consumption is achieved thanks to the sleep function embedded in the SRK2000 and the high voltage start-up circuit integrated in the L6563H.
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.
