General Description
The MAX16823 three-channel LED driver operates from a 5.5V to 40V input voltage range and delivers up to 70mA per channel to one or more strings of high-brightness LEDs (HBLEDs). Each channel’s current is programmable using an external current-sense resistor in series with the LEDs. Three DIM inputs allow a wide range of independent pulsed dimming in addition to providing the on and off control of the outputs. Wave-shaping circuitry reduces EMI while providing fast turn-on and turn-off times.
