LTpowerCAD and LTpowerPlanner
LTpowerCAD and LTpowerPlanner
The LTpowerCAD® program is a complete power supply design tool that guides users through the full regulator design process. LTpowerCAD suggests parts, provides recommendations and warnings, and shows all key performances including real-time efficiency and loop and transient response to easily optimize your design.
LTpowerPlanner is a system-level power architecture design tool created to help you design, optimize, and present the system-level block diagram or "power tree.” LTpowerPlanner is included with LTpowerCAD’s installation.
Key Features
- Part search according to user’s supply specification
- Guide the user to design and optimize circuit components
- Provide efficiency, feedback loop, and transient performances
- Provide a detailed summary of the design
- Export design to LTspice® for further simulations
- System-level power tree designs and optimizations using LTpowerPlanner
LTpowerCAD enables designers to find and design power solutions in five simple steps. Optimization of the power solution can be accomplished quickly and simply in this interactive environment. A detailed summary of the design will be provided by the tool.
The LTpowerPlanner tool within LTpowerCAD enables designers to create, compare, and optimize system-level power trees.
An LTpowerCAD design can be exported to LTspice for further time domain simulations.
