NCP1612A2規(guī)格書詳情
NCP1612A2屬于集成電路（IC）的PFC（功率因數(shù)校正）。由安森美半導體公司制造生產(chǎn)的NCP1612A2PFC（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體器件。不同模式包括平均電流、邊界導通、連續(xù)導通、臨界導通、電流控制式頻率折返、不連續(xù)和不連續(xù)導通，開關(guān)頻率從 6 kHz 至 1.7 MHz 可調(diào)。
The NCP1612 is designed to drive PFC boost stages based on an innovative Current Controlled Frequency Fold-back (CCFF) method. In this mode, the circuit classically operates in Critical conduction Mode (CrM) when the inductor current exceeds a programmable value. When the current is below this preset level, the NCP1612 linearly decays the frequency down to about 20 kHz when the current is null. CCFF maximizes the efficiency at both nominal and light load. In particular, the stand-by losses are reduced to a minimum.
General Features

? Valley Turn On
? High Drive Capability: ?500 mA/+800 mA
? VCC Range: from 9.5 V to 35 V
? Low Start-up Consumption
? Six Versions: NCP1612A, B, A1, A2, A3 and B2 (see Table 1)
? Line Range Detection
? pfcOK Signal
? This is a Pb-Free Device
Safety Features
? Separate Pin for Fast Over-voltage Protection (FOVP) for Redundancy
? Soft Over-voltage Protection
? Brown-out Detection
