IS31LT3957A HIGH VOLTAGE LED LIGHTING CONTROLLER

The IS31LT3957A 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.

IS31LT3957A Features

* Wide high voltage input range: 5V to 75V

* Supports boost, buck-boost, SEPIC and buck topology

* ±2% output current accuracy

* Adjustable operating frequency range of 100kHz~1MHz

* Programmable soft start to avoid inrush current

* Fixed under voltage lockout threshold
