The MAX16836 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 MAX16836 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 MAX16836 is well suited for applications requiring a 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 MAX16836 is available in a thermally enhanced, 5mm x 5mm, 16-pin TQFN package and in an 8-pin SO package with exposed pad. The MAX16836 is specified over the automotive -40°C to +125°C temperature range.
* Some packages have variations, listed on the drawing. "PkgCode/Variation" tells which variation the product uses. Note that "+", "#", "-" in the part number suffix describes RoHS status. Package drawings may show a different suffix character.
