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