PFC controller

Reduces power consumption and minimises audio noise

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.

Core advantages

High efficiency

Multi-protection function

High efficiency

With multiple operating modes such as CrM, DCM, Brust and AC follow, it is possible to reduce system losses as much as possible under different operating conditions;

Multi-protection function

Protection functions such as VDD UVLO, Brown in/out, ZCD OVP, FB OVP, OCP, ensure users' application reliability;
