General Description

The MAX16803 current regulator operates from a 6.5V to 40V input-voltage range and delivers up to a total of 350mA to one or more strings of high-brightness LEDs (HB LEDs).

The output current of the MAX16803 is adjusted by using an external current-sense resistor in series with the LEDs.

A dimming input allows widerange “pulsed” PWM operation.
