IR1150LS - uPFC One Cycle Control PFC IC

This page provides the datasheet information for the IR1150LS, a member of the IR1150S uPFC One Cycle Control PFC IC family.

Datasheet Summary

Description

The µPFC IR1150 is a power factor correction (PFC) control IC designed to operate in continuous conduction mode (CCM) over a wide range input line voltages.

The IR1150 is based on IR's proprietary "One Cycle Control" (OCC) technique providing a cost effective solution for PFC.

Features

  • PFC with IR proprietary “One Cycle Control” Continuous conduction mode (CCM) boost type PFC No line voltage sense required Programmable switching frequency (50kHz-200kHz) Programmable output overvoltage protection Brownout and output undervoltage protection Cycle-by-cycle peak current limit Soft start User initiated micropower “Sleep Mode”.
