The Texas Instruments LMR36506MSCEVM evaluation module help designers evaluate the operation and
performance of the LMR36506-Q1 wide-input buck converters. The LMR36506-Q1 is an easy-to-use
synchronous step-down DC/DC converter capable of driving up to 0.6 A of load current from an input
voltage of up to 65 V. The LMR36506MSCEVM features an output voltage of 5 V and a switching
frequency of 2.2 MHz. See the
