IS31LT3117 Datasheet (ISSI) - 4-CHANNEL CONSTANT CURRENT REGULATOR

IS31LT3117, 4-CHANNEL CONSTANT CURRENT REGULATOR

The IS31LT3117 is a 4-channel, linear regulated, constant current LED driver which can provide 4 equal currents outputs of up to 350mA per channel to drive high brightness LEDs over an input voltage range of 6V to 53V, while maintaining an output leakage current of less than 1µA.

IS31LT3117 Features

* a PWM input to enable simple dimming control using a digital control signal. The recommended frequency range of the PWM signal is 4kHz ~ 100kHz. The IS31LT3117 provides a unique over temperature protection scheme. A hard shutdown which turns off all LED currents occurs if the die junction temperatur
