The Texas Instruments LMR33630ARNXEVM and LMR33630CRNXEVM evaluation modules help
designers to evaluate the operation and performance of the LMR33630A and LMR33630C buck
regulators. The LMR33630 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 LMR33630xRNXEVMs
feature 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
