The MAX16835 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 MAX16835 is adjusted by using an external current-sense resistor in series with the LEDs. An enable input allows wide-range "pulsed" dimming. Wave-shaping circuitry reduces EMI. The differential current-sense input increases noise immunity. The MAX16835 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 components while providing ±3.5% output current accuracy. Additional features include a 5V regulated output and short-circuit and thermal protection.

The MAX16835 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.

Product Details

The MAX16836 evaluation kit (EV kit) demonstrates a current-controlled, high-output-current LED driver based on the MAX16836 current regulator. The EV kit is capable of supplying regulated output currents of up to 350mA and runs at supply voltages between 6.5V to 40V.

The MAX16836 EV kit features a PWM dimming control, user-selectable three-level output-current setting, and a 5V regulated output, which supplies up to 4mA of output current. The MAX16836 EV kit also evaluates the MAX16835 IC; contact the factory for a free sample of the MAX16835 IC.
