LT8374-1 - 1.2A Synchronous Step-Down LED Driver

Download the LT8374-1 datasheet PDF. This datasheet also covers the LT8374 variant, as both devices belong to the same 1.2a synchronous step-down led driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The LT®8374/LT8374-1 is a high efficiency, monolithic, synchronous step-down DC/DC converter with fixedfrequency and peak current control.

The LED current is programmed by a resistor from the CTRL pin to ground or by applying a PWM signal to the CTRL pin.
