To aid in the design of a SWIFT device, the SWITCHERPRO™ tool is available to automatically select the external components, such as the inductor, input and output capacitors, and even the compensation components, based on design requirements entered by the user. Once a schematic has been presented, the user can modify the components and optimize the design. A stress test, bode plot showing gain and phase margin, efficiency plot, bill of material spreadsheet, and a recommended layout are all quickly displayed. A What-If analysis can be performed to change the conditions of the power supply, such as the switching frequency and other parameters for the inductor and capacitors. The tool can either be used on-line, or downloaded onto the users personal computer. Visit http://www.ti.com/lsds/ti/analog/webench/overview.page for more information.
