IS32LT3957A - HIGH VOLTAGE LED LIGHTING CONTROLLER

The IS32LT3957A is a current mode PWM controller designed to drive a low side external NMOS FET for wide input/output voltage range and high LED current applications.

An external resistor senses the high side output current of the LED string.

A high side sense is the most flexible current sensing sc
