LT3744 - High Current Synchronous Step-Down LED Driver

General Description

The LT®3744 is a fixed frequency synchronous step-down DC/DC controller designed to drive a LED load at up to 20A continuous or 40A pulsed.

The peak current mode controller will maintain ±3% LED current regulation over a wide output voltage range, from VEE to VIN.

Key Features
