LMR23625CEVM: 3.3 or 5V @ 2.5A, 4.5 ~ 36V in, Buck

Summary

The Texas Instruments LMR23625CEVM evaluation module (EVM) helps designers evaluate the operation and performance of the LMR23625C wide-input Simple Switcher® buck regulator. This document describes the setup and the input / output connections of the EVM. Included are the board layout, schematic, and bill of materials.

The LMR23625 is a 36 V, 2.5 A step-down synchronous regulator with 75 µA quiescent current. With awide input range from 4.5 V to 36 V, it is suitable for a wide range of applications from automotive to industry for power conditioning from unregulated sources. The LMR23625CEVM evaluation board is designed to provide the design engineer to evaluate the LMR23625 series operation and performance.
