Description
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.
