Power Factor Controller for Compact and Robust Multimode Pre-Converters

Overview

TopologyPower Factor Correction
Switching frequency25-130 kHz
Output 1390 V / 1.3 A

Description

The NCP1655 is an innovative multimode power factor controller. The circuit naturally transitions from one operation mode to another depending the switching period duration so that the efficiency is optimized over the line/load range. In very−light−load conditions, the circuit can enter the soft−SKIP mode for minimized losses. Housed in a SO−9 package, the circuit further incorporates the features necessary for robust and compact PFC stages, with few external components.

Features

  • VS High−Voltage Line Sensing Pin: Reduced External Compoments Count and Minimized Leakage Current Compatible to Most Severe Standby Specifications (< 30 A @ 400 V)
  • Internal Compensation of the Regulation Loop
  • Fast Line / Load Transient Compensation (Dynamic Response Enhancer)
  • Large VCC Operating Range (9.5 V to 35 V)
  • Line Range Detection
  • pfcOK Signal For Enabling/Disabling the Downstream Converter
  • Jittering for Easing EMI Filtering

Typical applications

  • PC Power Supplies, All Off−Line Appliances Requiring Power Factor Correction
