GENERAL DESCRIPTION
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. The output current is easily programmed using a single, tiny external resistor. The outputs of the IS31LT3117 can be connected in parallel to allow greater than 350mA output current.

FEATURES
● 6V to 53V input supply voltage range
● Up to 1.4A total output current
● Over temperature protections
● Thermal current regulation above 130°C
● ±3% output current matching between channels
● PWM dimming and shutdown control input
● Optional 2.5V output to drive external standoff BJTs
● Very few external components

APPLICATIONS
● Industrial LED lighting
● Low EMI lighting applications
● Low-side constant current regulator
