Feb 21, 2011 IR1152S FIXED 66kHz FREQUENCY, PFC ONE CYCLE CONTROL PFC IC WITH BROWN-OUT PROTECTION Features VCC under voltage lockout PFC IC with IR proprietary One Cycle Control Programm able soft start Continuous conduction mode boost type PFC Micropower startup Fixed 66kHz switching frequency User initiated micropower Sleep Mode Average current mode control 750mA peak gate drive Input line sensed brownout protection Latch immunity and ESD protection Output overvoltage protection Open loop protection Cycle by cycle peak current limit Description Package PFC IR1152 power factor correction IC, based on IR proprietaryOne Cycle Contro (OCC) technique, provides for high PF 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 85-264VAC universal input, continuous conduction mode Boost PFC at fixed 66kHz switching frequency. IR1152 features include input-line sensed brown-out protection, overvoltage protection, cycle by cycle peak current limit, open loop protection, V UVLO, soft-start and micropower startup current of less CC than 75A. 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. The IR1152 is available in SO-8 packages.
