New from International Rectifier is the IR1150 family of mPFC (microPFC) for AC/DC power factor correction (PFC) circuits.

New from International Rectifier is the IR1150 family of mPFC (microPFC) for AC/DC power factor correction (PFC) circuits The compact SO-8-packaged device cuts PFC control board space in half, and enables a simplified and flexible high density solution for computing, industrial, consumer electronics and home appliances from 75W to 4kW

IR's new one cycle control (OCC) approach in the IR1150 delivers the performance of continuous conduction mode (CCM) PFC with the simplicity, reliability and low component count of a discontinuous current mode (DCM) circuit for PFC applications.

Power factor (PF) is the relationship between AC voltage and current waveforms and is a measure of "power quality" that affects the
