IR1150 - uPFC ONE CYCLE CONTROL PFC IC

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”.
