High-Voltage, 350mA, Adjustable Linear High-Brightness LED (HB LED) Driver
General Description
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 differential 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...
