User's Guide for the LMZM23601 and LMZM23600
Evaluation Boards
The evaluation modules (EVM) for the LMZM23601 and LMZM23600 are designed as easy-to-use
platforms to help evaluate the features and performance of these DC/DC step-down power modules. This
guide provides an overview of the board settings and board layout along with connection diagrams and
several performance curves for each device in the family.
