Feb 21, 2011 IR1152S FIXED 66kHz FREQUENCY, µPFC ONE CYCLE CONTROL PFC IC WITH BROWN-OUT PROTECTION Features • PFC IC with IR proprietary “One Cycle Control” • Continuous conduction mode boost type PFC • Fixed 66kHz 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” • 750mA peak gate drive • Latch immunity and ESD protection Description µPFC IR1152 power factor correction IC, based on IR proprietary "One Cycle Control" (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, 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. The IR1152 is available in SO-8 packages. http://www.DataSheet4U.com/ Package IR1152 Application Diagram ACIN1 - + VCC VOUT ACIN2 1 2 3 4 COM COMP ISNS GATE VCC VFB 8 7 6 5 + BOP OVP/EN IR1152 RTN www.irf.com © 2011 International Rectifier IR1152S Qualification Information Industrial Comments: This family of ICs has passed JEDEC’s Industrial qualification. IR’s Consumer qualification level is granted by extension of the higher Industrial level. MSL2 260°C (per IPC/JEDEC J-STD-020) Class A (per JEDEC standard JESD22-A115) Class 1A (per EIA/JEDEC standard EIA/JESD22-A114) Class I, Level A (per JESD78) Yes Qualification Level Moisture Sensitivity Level Machine Model ESD Human Body Model IC Latch-Up Test RoHS Compliant Absolute Maximum Ratings Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. All voltages are absolute voltages referenced to COM. Thermal resistance and power dissipation are measured under board mounted and still air conditions.
