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.
