com High-Voltage, 350mA LED Driver with Analog and PWM Dimming Control General Description The MAX16804 current regulator operates from a 5.
5V to 40V input voltage range and delivers 35mA to 350mA to one or more strings of high-brightness LEDs (HB LEDs).
The output current of the MAX16804 is set by using an external current-sense resistor in series with the LEDs.
A dual-mode DIM pin and on-board 200Hz ramp generator allow PWM dimming with an analog or PWM input signal.
The analog control signal at dimming input DIM allows for a theater-dimming effect to be implemented.
Fast turn-on and turn-off times ensure a wide-range PWM operation, while wave-shaping circuitry minimizes EMI.
The differential current-sense input increases LED current accuracy and noise immunity.
The MAX16804 is well suited for applications requiring high-voltage input and is able to withstand automotive load-dump events up to 45V.
An on-board pass element minimizes external comp...
