MAX16800ATE Datasheet PDF - Maxim Integrated

●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.
