L6561集成電路（IC）的PFC（功率因數(shù)校正）規(guī)格書PDF中文資料

L6561屬于集成電路（IC）的PFC（功率因數(shù)校正）。由意法半導(dǎo)體集團制造生產(chǎn)的L6561PFC（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)。

L6561 is the improved version of the L6560 standard Power Factor Corrector. Fully compatible with the standard version, it has a superior performant multiplier making the device capable of working in wide input voltage range applications (from 85V to 265V) with an excellent THD.

Furthermore the start up current has been reduced at few tens of mA and a disable function has been implement ed on the ZCD pin, guaranteeing lower current consumption in stand by mode.
