LM63635DNEVM Evaluation Module
The Texas Instruments LM63635DNEVM evaluation module (EVM) helps designers evaluate the operation
and performance of the LM63635Cx family of buck regulators. The LM63635Cx is a family of easy-to-use
synchronous step-down DC/DC converters capable of driving up to 3.25 A of load current from an input
voltage of 3.5 V to 36 V. See the LM63635 and LM63635C data sheets for additional features, detailed
description, and available options.
the LM63635DNEVM. Note that the EVM must be modified for use with some of these device numbers. See
Section 2
for more details.
