Maxim has introduced an adjustable linear current regulator that can provide up to 350 mA of current to one or more strings of high-brightness LEDs. A wide operating input-voltage range of 6,5 V to 40 V makes the new MAX16800 well-suited for automotive, commercial, and industrial applications, and helps protect it against large transients like those found in load-dump and cold cranking situations.
The MAX16800 combines an accurate current-sense reference with differential LED current-sensing to provide load accuracy of ±3,5%. This current accuracy allows consistent brightness for all light assemblies. Also, the device's low-dropout pass element (0,5 V typical) and low-voltage (204 mV) current-sense reference minimise power dissipation in the system.
Pulsed-width current dimming at the output is possible by pulsing the Enable input (EN) or by pulsing VMin. Wave-shaped circuitry generates soft-edges on pulse loads and reduces EMI during PWM dimming.
A fixed 5 V output regulator delivers up to 4 mA of load current for low-power applications throughout the 6,5 V to 40 V input-voltage range. The on-board 5 V regulator can power a microcontroller or other external components. Two small ceramic capacitors and a small sense resistor keep footprints very compact while minimising cost.
The MAX16800, in 5 x 5 mm 16-pin TQFN package, operates over -40 to +125°C, and features thermal and output short-circuit protection.
