Feb 21, 2011 IR1153S FIXED 22.2kHz FREQUENCY, PFC ONE CYCLE CONTROL IC WITH BROWN-OUT PROTECTION Features Cycle by cycle peak current limit PFC IC with IR proprietary One Cycle Control VCC under voltage lockout Continuous conduction mode boost type PFC Programmable soft start Fixed 22.2kHz switching frequency Micropower startup Average current mode control User initiated micropower Sleep Mode Input line sensed brownout protection 750mA peak gate drive Output overvoltage protection Latch immunity and ESD protection Open loop protection Description Package The PFC IR1153 power factor correction IC, based on IR proprietary One Cycle Contro (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 prote ction, VCC UVL O, soft- start and micropower startup current of less tha n 75A. In additio n, 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 pa ckage.
