The Texas Instruments LM63625QDRREVM 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 LM63625-Q1 features a selectable output voltage of 3.3 V or 5 V and a
switching frequency of 2.1 MHz. See the
down Voltage Converter Data Sheet
