... EVAL-ADP2503/ADP2504 Measuring Efficiency Measure the efficiency, η, by comparing the input power with the output power. × η = OUT OUT × 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 ...
