The MAX16823 evaluation kit (EV kit) circuit demonstrates
a current-controlled LED driver that uses the
MAX16823 current regulator. The EV kit is configured to
supply 50mA to each of the three output channels and
the circuit features 3 series LEDs per channel. Output
pads are provided at two channels to evaluate external
LEDs rated up to 70mA. Additional output pads are
available to evaluate LEDs rated up to 550mA (typ) on
one of the channels. The MAX16823 EV kit requires a
6.5V to 16V, 1A power supply for proper operation.
However, the MAX16823 IC can accept input voltages
from 5.5V to 40V.
The MAX16823 EV kit features pulse-width modulation
(PWM) dimming-control inputs and an open LED detection
output. The MAX16823 EV kit is a fully assembled
and tested printed circuit board (PCB).
