LM65460EVM Evaluation Module
Description
The Texas Instruments LM65460EVM evaluation
module (EVM) helps designers evaluate the operation
and performance of the LM654x0-Q1 family of wide
input voltage buck converters. The LM654x0-Q1
family are easy to use, synchronous, step-down
converters capable of supplying up to 4A, 6A, or 8A of
load current from an input voltage as high as 36V.
