!!! Excerpted from TI The Fly-Buck Design Calculator Tool assists designers with routine calculations for the 2W TPS55010 isolated DC/DC Converter. Two versions are available to support a single or a dual output configuration. The tool helps the user select a transformer, the sense resistors, and the power diode as well as the input, output, compensation, and primary capacitors. All equations used in the tool are shown with the corresponding datasheet equation. Primary and secondary waveforms of the voltage and current are also displayed.
