IR1153S Datasheet | International Rectifier

Features - PFC IC with IR proprietary “One Cycle Control” - Continuous conduction mode boost type PFC - Fixed 22.2k Hz switching frequency - Average current mode control - Input line sensed brownout protection - Output overvoltage protection - Open loop protection - Cycle by cycle peak current limit - VCC under voltage lockout - Programmable soft start - Micropower startup - User initiated micropower “Sleep Mode” - 750m A peak gate drive - Latch immunity and ESD protection 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 ponent count, PCB area and design time as pared to traditional solutions. The IC is designed to operate in continuous conduction mode Boost PFC converters with average current mode control at a fixed 22.2k Hz 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, softstart 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 75u A. IR1153 is available in SO-8 package. http://../ Package IR1153 Application Diagram ACIN1 + VOUT ACIN2 VCC 1 2 3 4 GATE P VCC ISNS VFB 8 7 6 5 BOP OVP/EN IR1144 IR1153 RTN .irf. © 2011 International Rectifier Qualification Information Industrial ments: This family of ICs has passed JEDEC’s Industrial qualification.
