MT7932 Overview
Description
The MT7932 is a single-stage, primary side control AC-DC LED driver with active power factor correction. The MT7932 integrates on-chip PFC circuit operates in discontinuous conduction mode (DCM) to achieve high power factor and low harmonic distortion (THD).
Key Features
- Single-stage Active PFC for high power factor and low THD (<8%)
- Primary side control eliminates opto-coupler
- High precision LED current (±3%)
- Up to 60W driving capability
- Cycle-by-cycle current limiting
- Under-voltage lockout (UVLO) protection
