LT3744 Datasheet (Linear Technology) - High Current Synchronous Step-Down LED Driver

LT3744, High Current Synchronous Step-Down LED Driver

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.
