SSC2005SC集成電路（IC）的PFC（功率因數(shù)校正）規(guī)格書PDF中文資料

SSC2005SC屬于集成電路（IC）的PFC（功率因數(shù)校正）。由三墾電氣株式會(huì)社制造生產(chǎn)的SSC2005SCPFC（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)。

General Description

SSC2005SC is a Critical Conduction Mode (CRM) control IC for power factor correction (PFC).

Since no input voltage sensing and no auxiliary winding for inductor current detection are required, the IC allows the realization of low standby power and the low number of external components. The product achieves high cost-performance and high efficiency PFC converter system.

Features and Benefits

? Inductor Current Detection (No auxiliary winding required)

? Low Standby Power (No input voltage sensing required)

? Minimum Off-time Limitation Function to restrict the Rise of Operation Frequency

? High Accuracy Overcurrent detection: ?0.60 V ± 5

? Protections

Overcurrent Protection (OCP): Pulse-by-pulse

Overvoltage Protection (OVP): Auto restart

FB Pin Undervoltage Protection (FB_UVP): Auto restart

Thermal Shutdown Protection with hysteresis (TSD): Auto restart

Applications

PFC circuit up to 200 W of output power such as:

? AC/DC power supply

? Digital appliances (large size LCD television and so forth).

? OA equipment (Computer, Server, Monitor, and so forth).

? Communication facilities
