IS32LT3957A Datasheet

Features and benefits


* Wide high voltage input range: 5V to 75V
* Supports boost, buck-boost, SEPIC and buck topology
* ±3.5% output current accuracy over -40°C ~ +125°C temperatu.

Application

An external resistor senses the high side output current of the LED string. A high side sense is the most flexible curr.

Description

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 .
