NCP1631 2-Phase Power Factor Controller

DATA SHEET www.onsemi.com Interleaved, 2-Phase Power Factor Controller NCP1631 The NCP1631 integrates 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.
