TDA16888G集成電路（IC）的PFC（功率因數(shù)校正）規(guī)格書PDF中文資料

TDA16888G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TDA16888GPFC（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)。
