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.

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.
