Product Summary

The IR1150STRPBF is a power factor correction (PFC) control IC designed to operate in continuous conduction mode (CCM) over a wide range input line voltages. The IR1150STRPBF is based on IRs 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 IR1150STRPBF is fully protected and eliminates the often noise sensitive line voltage sensing requirements of existing solutions.
