Buck converter l and c calculation
http://www.daycounter.com/Calculators/Switching-Converter-Calculator.phtml WebUse the actual output power to calculate the efficiency of the device: Efficiency = P OUT / P IN = 4.25W/5W = 85%. If the engineer had only measured OUT1, they would calculate an efficiency of 4.1W/5W = 82%. And if they had only measured OUT4, they would calculate an efficiency of 4.4W/6W = 88%.
