L6562A 400W FOT-controlled PFC pre-regulator evaluation board

Description

The board implements a 400 W, wide-range mains input, PFC pre-conditioner suitable for ATX PSU, Flat screen displays, etc. To make possible the use of a low-cost device like the L6562A at this power level, usually prohibitive for TM PFC, the chip operates with Fixed-Off-Time control. This allows continuous conduction mode operation, normally achievable with more expensive control chips and more complex control architectures.
