The NCP1632 integrates a dual MOSFET driver for interleaved PFC applications. Interleaving consists of two small stages connected in parallel, replacing one larger stage which is difficult to design. This approach has several advantages, such as simple implementation, the ability to use smaller components, and better heat dissipation. In addition, interleaving can also be extended to the power range of critical conduction mode operation which is energy efficient and cost effective (no need for low trr diodes). Additionally, the NCP1632 drivers are 180° phase shifted, which greatly reduces current ripple. Using SOIC16 encapsulation, the circuit combines all the functions required to build a robust and compact interleaved PFC stage with a minimal number of external components.
