LMR33630 EVM User’s Guide

The Texas Instruments LMR33630 EVM evaluation module (EVM) helps designers evaluate the operation
and performance of the LMR33630 buck regulator. The LMR336x0 is a family of easy-to-use synchronous
step-down DC/DC converters capable of driving up to 3 A of load current from an input voltage of 3.8 V to
36 V. The LMR33630 EVM features a selectable output voltage of 3.3 V or 5 V and a switching frequency
of either 400 kHz or 2.1 MHz. See the LMR33630 data sheet for additional features, detailed description,
and available options.

The EVM options are found in
