Simulation tool for POL DC/DC circuits

2 May 2012 Design Automation

Vishay recently introduced the PowerCAD Simulation tool, a free online tool that gives engineers a fast and convenient way to test and optimise DC/DC circuits built with Vishay Siliconix regulator ICs.

Using an intuitive interface, the tool supports both experienced analog and power designers as well as junior or digital designers with less experience in high-power, high­frequency voltage regulator design. Based on the required operating conditions, the engineer can select the appropriate regulator from the Vishay product offering and generate a full circuit schematic for the application. The schematic can then be edited as required for more advanced users or for performance comparison purposes.

Once the basic circuit is created, the designer can perform DC, transient and start-up simulations with visibility of all the circuit node waveforms. An efficiency analysis and optimisation of the circuit with detailed power loss analysis may also be performed.

Following these steps, the PowerCAD Simulation tool generates a bill of materials (BOM) available for online ordering, allowing a quick validation that reduces design cycle times. The circuit simulation can also be shared with Vishay FAEs for additional technical support or any other related question.

The PowerCAD Simulation tool can be found at www.vishay.com/power-ics/powercad-list
