The MAX16824 evaluation kit (EV kit) demonstrates a
high-voltage, 3-channel, linear high-brightness LED
(HB LED) driver using the MAX16824 IC. This EV kit is
configured to supply an LED current of 100mA per
channel and operates from a 0.5A, 6.5V to 28V rated
power supply.
The EV kit eases evaluation of the MAX16824 pulse-
width-modulation (PWM) dimming-control feature by
providing three independent PWM inputs to all three
channels. Each PWM input accepts a digital signal up
to 5kHz.
