Product Details

The MAX20028 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB that contains all the components necessary to evaluate the MAX20028 power-management IC (PMIC). The EV kit includes one high-voltage step-down controller and two low-voltage step-down converters.

The EV kit can operate from 3.5V to 36V input voltages and is optimized for automotive infotainment applications. The high-voltage controller is configured for a 5V output that provides at least 5A. The low-voltage step-down converters are configured for 3.3V and 1.2V, each providing up to 3A. The EV kit can be easily reconfigured to operate in continuous PWM mode, skip mode, or external synchronization operation.

The EV kit comes with MAX20028ATJA/VY+ device installed, but is capable of evaluating other variants of the MAX20028 IC. Refer to the MAX20028 IC data sheet for external component selection.
