LMR22007YMINI-EVM: 3.3V @ 750mA, 4.5 ~ 20V in

Summary

The Texas Instruments LMR22007 is a PWM DC/DC buck (step-down) regulator with an adjustable input current limit. With a wide input range from 2.7V-20V, it is suitable for a variety of applications. The LMR22007 demonstration board is designed to provide the design engineer with a fully functional power converter based on the buck topology to evaluate the LMR22007 series of buck regulators.
