MT7933 Overview
Description
MT7933 is a single-stage，primary side control AC-DC LED driver with active power factor correction. MT7933 integrates on-chip PFC circuit operates in critical conduction mode (CRM) to achieve high power factor and reduce the power MOSFET switching loss.
Key Features
- Single-stage Active PFC for high power factor and low THD
- Primary side control eliminates opto-coupler
- High precision LED current (+/-3%)
- Critical Conduction Mode operation
- Up to 20W driving capability
- Cycle-by-cycle current limit
