Description
The L6562A is a current-mode PFC controller
operating in transition mode (TM). With the same
pin-out as its predecessor L6562, the L6562A
offers improved performance mainly in terms of
efficiency and noise immunity.
This board implements an 80 W, wide-range
mains input and a PFC pre-conditioner suitable
for ballast, adapters, flat screen displays, etc.
