Overview

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.

Key Features

  • necessary for building robust and compact interleaved PFC stages, with a minimum of external components. General Features.
  • Near.
  • Unity Power Factor.
  • Substantial 180 Phase Shift in All Conditions Including Transient Phases.
  • Frequency Clamped Critical Conduction Mode (FCCrM) i. e. , Fixed Frequency, Discontinuous Conduction Mode Operation with Critical Conduction Achievable in Most Stressful Conditions.
  • FCCrM Operation Optimizes the PFC Stage Efficiency Over the Load Rang.
