Product Details

The MAX20356 evaluation kit (EV kit) is a fully assembled and tested circuit for evaluating the MAX20356 power-management solution designed for ultra-low-power wearable applications.

A flexible set of power-optimized voltage regulators, including 3 x buck converters, a buck-boost converter, 4 x linear regulators, including an RTC LDO, and 3 x load switches, provide a high level of integration and the ability to create a fully optimized power architecture. Refer to the MAX20356 IC data sheet for detailed information regarding the operation and features of the devices.

The device is configurable through an I²C interface that allows for programming various functions and reading device status. The EV kit GUI application sends commands to the MAXPICO2PMB# adapter board to configure the device.

The EV kit comes standard with the MAX20356 EV kit version IC installed
