描述

The MAX38802 evaluation kit (EV kit) serves as a reference platform for evaluating the MAX38802 voltage regulator IC. This single-chip, integrated switching regulator provides an extremely compact, highly efficient, fast, accurate, and reliable power-delivery solution for low-output voltage applications. The MAX38802 has different programmability options to enable a wide range of configurations.

The EV kit consists of a fully-assembled and tested Printed Circuit Board (PCB) implementation of the MAX38802. Jumpers, test points, and input/output connectors are included for flexibility and ease-of-use. Refer to the data sheet for ordering information and more details.
