1 Content
The evaluation board described here is a 300W power factor correction (PFC) circuit with 85~265VAC
universal input and 393VDC fixed output. Boost converter topology is employed in this board. The
continuous conduction mode (CCM) PFC controller
ICE2PCS01
is employed in this board to achieve
the unity power factor. The switching frequency is programmable by external resistor at one pin.
There are various protection features incorporated to ensure safe system operation conditions. The
device has a unique soft-start function which limits the start up inrush current thus reducing the stress
on the boost diode. To improve the efficiency, the third generation
CoolMOS™
is used as the power
switch due to its lowest area specific Rdson. High voltage Silicon Carbide (SiC) Schottky diode
thinQ!™
is used as PFC boost diode. Because of its ideal reverse recovery behavior, SiC Schottky
diode is extremely suitable for high frequency CCM PFC application.
