MT7932 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). With MAXIC Proprietary control technique, precision LED current is achieved without secondary side sense and feedback circuit including opto-coupler.
MT7932 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
