RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

10    DC Power Budget


On this worksheet, cells are provided for entering the power supply voltages and currents for each device. Efficiencies are also assigned to each supply to permit the total system input power to be calculated.


Enter the supply voltage(s) in the cells at the top. Negative values do not affect the power calculation. The titles of the current and power columns will automatically change to reflect the values entered for the voltages.


Enter the efficiency of each supply to permit a total system power requirement to be calculated. Enter “100” for the efficiency otherwise.
