The MAX16839 evaluation kit (EV kit) demonstrates
three separate high-voltage, single-channel, linear high-
brightness LED (HB LED) drivers using the MAX16839
IC. This EV kit is configured to supply an HB LED current
of 100mA per channel and operates from a 5V to 40V
rated power supply providing up to 300mA. The EV kit
can withstand a 45V automotive load-dump condition.
An input switch is included to evaluate pulse-width-
modulation (PWM) driving with supply chopping.
The EV kit eases evaluation of the MAX16839 PWM
dimming-control feature by providing three indepen-
dent PWM inputs to all three channels. Each PWM input
accepts a digital signal up to 10kHz. Additionally, mul-
tiple EV kits can be cascaded by using the MAX16839
FLTS signals. An input common-mode choke is also
provided to facilitate EMI immunity testing.
