LMR36506RREVM User’s Guide

The Texas Instruments LMR36506RREVM evaluation module help designers evaluate the operation and
performance of the LMR36506 wide-input buck converters. The LMR36506 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 LMR36506RREVM features an output voltage of 3.3 V or 5 V and a switching frequency of 1
MHz. See the
