High-Voltage, 350mA, Adjustable Linear
High-Brightness LED (HB LED) Driver
General Description
Features
The MAX16800 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.
The output current of the MAX16800 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 dif-
ferential current-sense input increases noise immunity.
The MAX16800 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 ele-
ment minimizes external components while providing
±3.5% output current accuracy. Additional features
include a 5V regulated output and short-circuit and
thermal protection.
The MAX16800 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.
