NCP1632 集成了双 MOSFET 驱动器，适用于交错式 PFC 应用。交错式是指并联两个小级来代替较大的级，设计起来更困难。这种方法有几个优点，例如易于实施、使用较小的元件或更好地分布热量。此外，交错式扩展了临界导通模式的功率范围，这是一种高效且经济实惠的技术（无需低 trr 二极管）。此外，NCP1632 驱动器具有 180o 相移，可显著降低电流纹波。该电路采用 SOIC16 封装，集成了构建坚固紧凑的交错式 PFC 级所需的所有功能，并且外部元件最少。

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.
