Evaluation Kit for the MAX16821B

Please check latest availability status for a specific part variant.


The MAX16821B evaluation kit (EV kit) is a fully assembled and tested surface-mount printed-circuit board (PCB) designed to evaluate the MAX16821B pulse-width-modulation (PWM) LED driver controller in a boost configuration.

The MAX16821B EV kit operates from a DC supply voltage of 7V to 24V. The EV kit's output is configured to deliver 660mA of current into series LED string with a maximum forward voltage of 28V. The LED brightness can be dimmed using a digital PWM signal.

The EV kit provides an option to configure the MAX16821B IC's overvoltage protection, switching frequency, and frequency compensation. The MAX16821B EV kit also features a clock output PCB pad to drive a second LED current regulator out-of-phase.
