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, V

CC

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.
