Linear LED driver powers 20A constant current

One to note maybe: LED driver powers 20A constant current, says Linear Technlogy.

It has introduced a synchronous step-down DC-DC converter that will deliver a 20A current to drive high current LEDs, writes Richard Wilson.

The LT3743 will drive up to 20A of continuous LED current from a nominal 12V input, delivering more than 80W of power. In pulsed applications, it can deliver up to 40A of LED current or 160W from a 12V input.
