The LTpowerCAD design tool is a Microsoft Excel based power supply design tool program that can significantly ease the tasks of power supply design with Linear Technology µModule and some monolithic products. Unlike conventional simulation tools, this tool guides users throughout the whole supply design process: it searches suitable LTC parts according to user’s supply specifications; then it guides the user to select and optimize circuit component values with suggestions and warnings. The tool shows real-time results of feedback loop bode plot, as well as the power stage performance. The design can be exported to LTspice; simulation circuit for users to further verify their designs. The tool also provides PCB layout example and a design summary. Currently, this design tool support Microsoft Excel 2000, 2002, 2003, 2007 and 2010 on a Windows based computer.
