Product Details

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 independent PWM inputs to all three channels. Each PWM input accepts a digital signal up to 10kHz. Additionally, multiple EV kits can be cascaded by using the MAX16839 FLTS signals. An input common-mode choke is also provided to facilitate EMI immunity testing.
