Description
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 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.
