최대 작동 온도 = +125 °C Width = 4mm The NCP1632 integrated a dual MOSFET driver for interleaved PFC applications. Interleaving consists of paralleling two small stages in lieu of a bigger one, more difficult to design. This approach has several merits like the ease of implementation, the use of smaller components or a better distribution of the heating. Also, Interleaving extends the power range of Critical Conduction Mode that is an efficient and cost-effective technique (no need for low trr diodes). In addition, the NCP1632 drivers are 180o phase shifted for a significantly reduced current ripple. Housed in a SOIC16 package, the circuit incorporates all the features necessary for building robust and compact interleaved PFC stages, with a minimum of external components.180° out of phase operation Low EMI and reduces RMS current in the bulk capacitor Frequency Clamped Critical conduction Mode (FCCrM) operation Optimize efficiency over the load range Frequency foldback at low power Improve light load efficiency Integrated Overcurrent protection, Overvoltage protection, UVLO and brown-out protection Increase system reliability Applications All Off Line Appliance Requiring Power Factor Correction SMPS Flat panel TVs Computer Power Supplies LCD TV Server power, networking power
