Input Power/Current Calculation for IC693PWR328 Power Supply
Ŷ Determine total output load from typical specifications listed for individual modules in
Chapter 2.
Ŷ Use the graph to determine average input power.
Ŷ Divide the input power by the operating source voltage to determine the input current
requirements.
Ŷ Use the lowest input voltage to determine the maximum input current.
Ŷ Allow for start-up surge current requirements.
Ŷ Allow margins (0% to 20%) for variations.
