ICE3PCS01G集成电路（IC）的PFC（功率因数校正）规格书PDF中文资料

ICE3PCS01G属于集成电路（IC）的PFC（功率因数校正）。由英飞凌科技股份公司制造生产的ICE3PCS01GPFC（功率因数校正）功率因数校正 (PFC) 是用于调整交流电路中的电压和电流之间的相位角，使之趋近于零的半导体器件。不同模式包括平均电流、边界导通、连续导通、临界导通、电流控制式频率折返、不连续和不连续导通，开关频率从 6 kHz 至 1.7 MHz 可调。

描述 Description

The ICE3PCS01G is a 14-pins wide input range controller IC for active power factor correction converters. It is designed for converters in boost topology, and requires few external components. Its power supply is recommended to be provided by an externalauxiliary supply which will switch on and off the IC.
