Package
The µPFC IR1150 is a power factor correction (PFC) control IC designed to operate in continuous
conduction mode (CCM) over a wide range input line voltages. The IR1150 is based on IR's
proprietary "One Cycle Control" (OCC) technique providing a cost effective solution for PFC.
The proprietary control method allows major reductions in component count, PCB area and
design time while delivering the same high system performance as traditional solutions.
The IC is fully protected and eliminates the often noise sensitive line voltage sensing requirements
of existing solutions.
The IR1150 features include programmable switching frequency, programmable dedicated
8-Lead SOIC
over voltage protection, soft start, cycle-by-cycle peak current limit, brownout, open loop,
UVLO and micropower startup current.
In addition, for low standby power requirements (Energy Star, 1W Standby, Blue Angel, etc.), the IC can be driven into sleep
mode with total current consumption below 200µA, by pulling the OVP pin below 0.62V.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltages are
absolute voltages referenced to COM. Thermal resistance and power dissipation are measured under board mounted and
still air conditions.

Electrical Characteristics
The electrical characteristics involve the spread of values guaranteed within the specified supply voltage and junction
temperature range TJ from – 25 ° C to 125°C. Typical values represent the median values, which are related to 25°C. If not
otherwise stated, a supply voltage of VCC =15V is assumed for test condition
