The MAX16835 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 MAX16835 is
adjusted by using an external current-sense resistor in
series with the LEDs. An enable input allows wide-
range “pulsed” dimming. Wave-shaping circuitry
reduces EMI. The differential current-sense input
increases noise immunity. The MAX16835 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 compo-
nents while providing ±3.5% output current accuracy.
Additional features include a 5V regulated output and
short-circuit and thermal protection.
The MAX16835 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.
Applications
Automotive Interior: Map, Courtesy, and Cluster
Lighting
Automotive Exterior: Tail Lights and CHMSL
Warning Lights for Emergency Vehicles
