Interleaved, 2-Phase Power Factor Controller
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 ponents 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 NCP1631 drivers are 180 phase shift for a significantly reduced current ripple.
