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. MT7930 integrates power factor correction function and works in DCM and constant OFF time mode. A small harmonic current emission (THD) is achieved. MT7930 is also implemented with various protections, such as over-current protection (OCP), over-voltage protection (OVP), short-circuit protection (SCP) and over-temperature protection (OTP), etc, to ensure a reliable system.

FEATURES
Wide input voltage range from AC85V to AC265V
Highly accurate constant LED current (+/-3%)
Up to 80W 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
