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 c.
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. ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ Features +6.5V to +40V Operating Range Adjustable LED Current (35mA to 350mA) ±3.5% LED Current Accuracy High-Voltage DIM Pin for Dimming Interface Integrated Pass Element with Low-Dropout Voltage (0.5V typ) +5V Regulated Output with 4mA Source Capability Parallel Operation for LED Current > 350mA Differential LED Current Sense Low Shutdown .
