DESCRIPTION
MT7930 is a single-stage, primary side control AC-DC LED driver with high power factor. With MAXIC patent pending technology, the LED current can be regulated accurately through sensing the primary side information with few external components without the need of an opto-coupler.
FEATURES
● Wide input voltage range from AC85V to
AC265V
● Highly accurate constant LED current
(+/-3%)
● Up to 50W power drivability.
● Primary-side current sensing and regulation
without an opto-coupler
● Leading edge blanking (LEB) technique
● 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
● Available in SOP8 package
APPLICATIONS
● AC/DC LED driver applications
● General purpose constant current source
● Signal and decorative LED lighting
● E14/E27/PAR30/PAR38/GU10 LED lamp
