 Details
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 high-
brightness LED (HB LED) loads. The output current is
adjusted by using an external current-sense resistor in
series with the LEDs. The MAX16815/MAX16828’s dim-
ming input allows wide-range “pulsed” PWM operation.
An on-board pass element minimizes external compo-
nents while providing ±3.5% output-current accuracy.
The MAX16815/MAX16828 are available in a thermally
enhanced, 3mm x 3mm, 6-pin TDFN package with
exposed pad and in an 8-pin SO package with
exposed pad; they are specified over the automotive
-40°C to +125°C temperature range.
