DESCRIPTION
Primary-side Fly-back control without the photo-coupler Universal Input Voltage Range from 90VAC to 264VAC Transition-mode PFC operating Built-in Active Power Factor Correction Technique Constant Output Current Control LED driver Good Line and Load Regulation Open-LED Protection on DMG pin Over-Voltage Protection on VCC pin Short-LED Protection Cycle by Cycle Over current Protection on CS pin Over-Temperature Protection Gate Driving Voltage Clamping SOT26 Package Available
AT7373 is a primary-side Fly-back control IC with active power factor correction function for LED lighting application.
The IC achieves high power factor and low THD operation by BCM mode. The line and load regulation of LED current is about ±3% because of particular control method.
AT7373 also provides gate driving voltage clamping, VCC over voltage protection and system output open/short...
