Nov 3, 2010 PRELIMINARY IR1145SPBF 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 P rogrammab le 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 IR1145 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. IR1145 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 150A. 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 150uA. The IR1145 is available in SO-8 packages.
