G5991 Overview
The G5991 is current mode control LED driver IC designed to control single switch PWM converter in a constant frequency. External current sense resistor and slope pensation resistor make it flexible for various applications. A PWM dimming input controls a duty ratio from 0% to 100% with frequency up to few kilohertz.
