IR1155S - uPFC ONE CYCLE CONTROL PFC IC

Datasheet Summary

Description

The μPFC IR1155 power factor correction IC, based on IR proprietary "One Cycle Control" (OCC) technique, provides for high PF, low THD and excellent DC Bus regulation while enabling drastic reduction in component count, PCB area and design time as compared to traditional solutions.

Features

  • PFC IC with IR proprietary “One Cycle Control”.
  • Continuous conduction mode boost type PFC.
  • Programmable switching frequency (48k-200kHz).
  • Average current mode control.
  • Output overvoltage protection.
  • Open loop protection.
  • Cycle by cycle peak current limit.
  • VCC under voltage lockout.
  • Programmable soft start.
  • Micropower startup.
  • User initiated micropower “Sleep Mode”.
  • OVP/EN pin internal fil.
