Maxim Integrated
General Description
The MAX16815/MAX16828 current regulators operate from a 6.5V to 40V input voltage range and deliver up to 100mA (MAX16815) or 200mA (MAX16828) to highbrightness LED (HB LED) loads. The output current is adjusted by using an external current-sense resistor in series with the LEDs.
