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

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 60W driving capability.
• Cycle-by-cycle current limiting
• Under-voltage lockout (UVLO) protection
• VDD and output over voltage protection
• Adjustable constant current and output
   power setting
• Power on soft-start
• Compact SOT23-6 package

APPLICATIONS
• AC/DC LED driver applications
• Signal and decorative LED lighting
• E27/PAR30/PAR38/GU10 etc.LED lamp
• T8/T10 LED String
