G5991 Datasheet (Global Mixed-mode Technology)

G5991, High Current LED Driver

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 compensation resistor make it flexible for various applications.

A PWM dimming input controls a duty ratio from 0% to 100% with frequency
