Resumen del producto
EVL6562A-400W is a evaluation board for L6562A 400W FOT controlled PFC pre regulator. The board implements a 400W, 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, the chip operates with Fixed Off Time control. In this PFC operating mode the Toff is kept constant and the Ton is free to be changed in order to modulate the power drained from the source according to the load. Peak current mode FOT control provides an unconditionally stable inner current loop with no gain peaking and shows dead beat control characteristics.
