MAX16836ATE+

The MAX16836ATE+ from Maxim Integrated Products is a high voltage, 350mA, high brightness LED driver with PWM dimming and 5V regulator in 16 pin TQFN package. This 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 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. Typical applications include emergency vehicle warning lights, indicators, general lighting, signage and beacons.
