IR1150S - UPFC ONE CYCLE CONTROL PFC IC

Download the IR1150S datasheet PDF. This datasheet also covers the IR1150IS variant, as both devices belong to the same upfc one cycle control pfc ic family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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”.
