 Design Tools
ADIsimPower™ Voltage Regulator Design Tool
This tool supports buck converter designs OPTIMIZED for efficiency, PCB space, cost, or part count. The user enters five design parameters and selects a design goal. The tool calculates optimal values to produce a complete schematic, BOM, efficiency plot, and a performance summary. The BOM includes vendor part numbers and also allows the user to make alternative part choices. A complete design is documented with a PDF ready to print or email.
