LM63625EVM EVM User’s Guide
The Texas Instruments LM63625EVM evaluation module (EVM) helps designers evaluate the operation
and performance of the LM63625-Q1 buck regulator. The LM63625-Q1 is a family of easy-to-use
synchronous step-down DC/DC converters capable of driving up to 2.5 A of load current from an input
voltage of 3.5 V to 36 V. The LM63625EVM features a selectable output voltage of 3.3 V or 5 V and a
switching frequency of 2.1 MHz . See the
LM636x5-Q1 3.5-V to 36-V, 1.5-A, and 2.5-A Automotive Step-
down Voltage Converter Data Sheet for additional features, detailed description, and available options.
The EVM options are found in Table 1 .
