LT3743 High Current Synchronous Buck LED Driver with Three-State Control - Video Product Brief

Jeff Gruetter - Product Marketing Engineer Mar 4th 2011
The LT3743 is a fixed frequency synchronous step-down DC/DC controller designed to drive high current LEDs. The average current mode controller will maintain inductor current regulation over a wide output voltage range of 0V to (VIN – 2V). LED dimming is achieved through analog dimming on the CTRL_L, CTRL_H and CTRL_T pins ...

DC1470A - LT3743EUF Demo Board | High Current Step-Down LED Driver Controller, 6.5V ≤ VIN ≤ 24V, VLED = 6V @ 20A

Jan 7th 2010
Demonstration circuit 1470 is a High Current Synchronous Step-Down LED Driver with Three-State Control featuring the LT3743EUFD. The demo board is optimized for 20A output from a 12V input. Being an LED driver, the output current is regulated until the output voltage reaches a programmed voltage limit. The voltage limit on this ...

High Current LED Driver with Three-State Control

Walker Bai - Applications Enginneer Nov 15th 2009
There are many LED drivers on the market for low current LEDs and many others for high current LEDs. Low current LEDs are 20mA to 100mA LEDs. High current ones are 100mA to ~1A. But how many 20A LED drivers do you know? How about 40A? Not many. How about super fast µs rise time between 0A and 20A or between any two current ...
