STMicroelectronics L6563/L6563A Advanced Transition-Mode PFC Controller Datasheet
The L6563 and L6563A are current-mode PFC controllers operating in Transition Mode (TM), designed for PFC pre-regulators in AC-DC adapters, desktop PCs, and servers. The L6563 offers improved performance with a highly linear multiplier and special correction circuits to reduce crossover distortion, enabling wide-range mains operation with low Total Harmonic Distortion (THD). It includes features such as very precise adjustable output overvoltage protection, tracking boost function, and protection against feedback loop failure. The L6563A is similar but lacks the inductor saturation detection function found in the L6563.

From: STMicroelectronics L6563/L6563A Advanced Transition‑Mode PFC Controller Datasheet
What is the supply voltage range for the L6563/L6563A?
The device operates with a supply voltage between 10.3 V and 22 V.
From: ST L6563/L6563A Advanced Transition‑Mode PFC Controller Datasheet
What start‑up current does the controller draw?
The start‑up current is specified as 50 µA to 90 µA.
From: ST L6563/L6563A Advanced Transition‑Mode PFC Controller Datasheet
What protection does the L6563 have that the L6563A lacks?
The L6563 includes an inductor‑saturation detection function that stops the PFC stage if the boost inductor saturates; this function is not present in the L6563A.
