Infineon IR1153STRPBF

Непрерывная проводимость (CCM)22,2 кГц

Overview

The μPFC IR1153 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. The IC is designed to operate in continuous conduction mode Boost PFC converters with average current mode control at a fixed 22.2kHz switching frequency. The IR1153 features include input-line sensed brown-out protection, dedicated pin for over voltage protection, cycle by cycle peak current limit, open loop protection, VCC UVLO, soft start and micropower startup current of less than 75µA. In addition, for standby power requirements, the IC can be driven into a micropower sleep mode by pulling the OVP/EN pin low where the current consumption is less than 75uA. IR1153 is available in SO-8 package.
