STNRGPF12

Power Management - Specialized Overview

The STNRGPF12 is a digital power factor controller designed for high-performance industrial applications. It supports mixed-signal average current mode control in continuous conduction mode (CCM) at a fixed switching frequency of 60 kHz. The device manages input voltage ranges from 90 to 265 V AC and line frequencies between 47 and 63 Hz. It enables up to two interleaved PFC channels, achieving a power factor greater than 0.98 at 20% load and total harmonic distortion less than 5% at 20% load. The controller integrates cycle-by-cycle regulation via an analog current control loop and features digital inrush current limitation.
