300W PFC Evaluation Board with CCM PFC controller ICE2PCS02
The evaluation board is a 300W power factor correction (PFC) circuit with 85~265VAC universal input and 393VDC fixed output. The continuous conduction mode (CCM) PFC controller ICE2PCS02 is employed in this board to achieve the unity power factor. This ICE2PCS02 is a design variant of ICE2PCS01 to incorporate the new input brown-out protection function. Appreciated for its high integrated design, ICE2PCS02 can achieve full requirements of the PFC application implemented in the 8-pin DIP8 and SO8 packages. At the same time the number of peripheral components is minimized. The operation frequency is fixed at 65kHz due to internal oscillator of ICE2PCS02. In order to improve the power conversion efficiency, the CoolMOS™ C3 series and high voltage silicon carbide (SiC) schottky diode thinQ!TM are used into this boost type PFC circuit.
