MAX16820EVKIT+: 1A @ 20V Max, 5 ~ 28V in

Summary

The MAX16820 evaluation kit (EV kit) demonstrates a step-down, constant-current, hysteretic controlled switching regulator for driving high-brightness LEDs (HB LEDs) using the MAX16820 controller IC. This EV kit is configured to supply an average output LED current of 1A, and operates from a 5V to 28V supply.

The EV kit eases evaluation of the MAX16820 dedicated pulse-width-modulation (PWM) dimming control and undervoltage lockout (UVLO) features.

The MAX16820 EV kit comes with the MAX16820 installed. The MAX16820 EV kit can also be used to evaluate the MAX16819. Contact the factory for free samples of the pin-compatible MAX16819 to evaluate this part.
