Measuring Efficiency
Measure the efficiency, η, by comparing the input power with
the output power.
Measure the input and output voltages as close as possible to the
input and output capacitors to reduce the effect of IR drops.

Measuring Inductor Current
Measure the inductor current by removing one end of the
inductor from its pad and connecting a current loop in series.
Then, use a current probe to measure the current flowing
through the current loop.
