MC33232集成電路（IC）的PFC（功率因數(shù)校正）規(guī)格書PDF中文資料

MC33232屬于集成電路（IC）的PFC（功率因數(shù)校正）。由安森美半導(dǎo)體公司制造生產(chǎn)的MC33232PFC（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)。

The MC33232 is the monolithic Integrated Circuit using the SMARTMOS? process as the new technology. And is active power factor controller specially design for use as off?line power converter application. This integrated circuit features an internal startup timer for stand?alone application, a one quadrant multiplier for near unity power factor, zero current detector to ensure critical condition operation, transconductance error amplifier, quickstart circuit for enhanced startup, trimmed internal bandgap reference, current sensing comparator, a totem pole output ideally suited for drive a power MOSFET, and a one shot?rigger circuit to eliminate a problem at the light loading.
