PFC controller

Reduces power consumption and minimises audio noise

PFC controllerPFC controller

Overview

Power Factor Correction (PFC) Controller. High-performance performance using a multi-mode control strategy. Operates in critical conduction mode (CrM) under heavy load. Operates in Discontinuous Conduction Mode (DCM) under light load. Under no load, the IC will operate in burst mode to reduce power consumption and minimise audio noise.
