Series: MAX16803
RoHS: Unknown
View Datasheet Manufacturer Site View Pricing & Stock

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. 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 components 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. The MAX16836 is a newer and more cost effective product; except for different PWM dimming current slew rates, it provides the same performance and is pin-to-pin compatible with the MAX16803.
