These tools shorten design time and optimize your power supply solution before you build your prototype board. For more information and design support, contact a local sales office www.linear.com/contact LTpowerCAD Ⅱ LTpowerCAD® is a free download and easy-to-use power supply design tool with a user-friendly graphical user interface (GUI) and powerful design features. It helps power supply designers select a solution for given supply specifications, design power stage components, estimate regulator efficiency and power loss, and optimize supply loop stability and load transient performance. It is a fast off-line tool that runs on Windows PCs, and includes a sync-release feature to ensure your program and its solution libraries are up-to-date. Once a circuit design is completed, it is easily exported to the LTspice® simulation platform. Inside the LTpowerCAD toolbox, there is also an LTpowerPlanner system architecture tool for system-level power management design and optimization.
