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 wide-

range “pulsed” PWM operation. Wave-shaping circuitry

reduces EMI. The differential current-sense input

increases noise immunity. The MAX16803 is well suited

for applications requiring high-voltage input and is able

to withstand automotive load-dump events up to 40V.

An on-board pass element minimizes external compo-

nents while providing ±3.5% output-current accuracy.

Additional features include a 5V regulated output and

short-circuit and thermal protection.

The MAX16803 is available in a thermally enhanced,

5mm x 5mm, 16-pin TQFN package and is specified

over the automotive -40°C to +125°C temperature range.
