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.
