LMR23630AEVM: 3.3 or 5V @ 3A, 4.5 ~ 36V in, Buck

Summary

The Texas Instruments LMR23630AEVM evaluation module (EVM) helps designers evaluate the operation and performance of the LMR23630A 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 LMR23630 is a 36 V, 3A step-down synchronous regulator with 75µA quiescent current. With a wide input range from 4.5V to 36V, it is suitable for a wide range of applications from automotive to industry for power conditioning from unregulated sources. The LMR23630AEVM evaluation board is designed to provide the design engineer to evaluate the LMR23630 series operation and performance.
