LT3745-1 - 16-Channel 50mA LED Driver

General Description

The LT®3745-1 integrates a 16-channel LED driver with a 55V buck controller.

The LED driver lights up to 75mA/36V of LEDs in series per channel, and the buck controller generates an adaptive bus voltage supplying the parallel LED strings.
