Description

The L6562A is a current-mode PFC controller operating in transition mode (TM). With the same pinout as its L6562 predecessor, the L6562A offers improved performance mainly in terms of efficiency and noise immunity.

The STEVAL-ISA102V1 implements an 80 W, wide-range mains input and a PFC pre-conditioner suitable for ballast, adapters, flat screen displays, etc.
