ICE3PCS03G集成電路（IC）的PFC（功率因數(shù)校正）規(guī)格書PDF中文資料

ICE3PCS03G屬于集成電路（IC）的PFC（功率因數(shù)校正）。由英飛凌科技股份公司制造生產(chǎn)的ICE3PCS03GPFC（功率因數(shù)校正）功率因數(shù)校正 (PFC) 是用于調(diào)整交流電路中的電壓和電流之間的相位角，使之趨近于零的半導(dǎo)體器件。不同模式包括平均電流、邊界導(dǎo)通、連續(xù)導(dǎo)通、臨界導(dǎo)通、電流控制式頻率折返、不連續(xù)和不連續(xù)導(dǎo)通，開關(guān)頻率從 6 kHz 至 1.7 MHz 可調(diào)。

Description

The ICE3PCS03G is a 8-pins wide input range controller IC for active power factor correction converters. It is de signed for converters in boost topology, and requires few external components. Its power supply is recommended to be provided by an external auxiliary supply which will switch on and off the IC.
