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
