EVL6562A-400W L6562A 400W FOT-controlled PFC pre-regulator evaluation board

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. For technical details and demoboard performance, please refer to the available application note.
