Online simulation tool targets DC/DC circuits

Vishay Intertechnology Inc. has unveiled a free online tool that the company said gives engineers a fast and convenient way to test and optimize DC/DC circuits built with Vishay Siliconix microBUCK regulator ICs. The PowerCAD Simulation tool claims to use an intuitive interface that supports both experienced analog and power designers as well as junior or digital designers in high-power, high-frequency 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, stated the company. 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 startup simulations with visibility of all the circuit node waveforms. An efficiency analysis and optimization of the circuit with detailed power loss analysis may also be performed, added Vishay.

The PowerCAD Simulation tool generates BOM available for online ordering, allowing a quick validation that dramatically reduces design cycle times, boasted the company. The circuit simulation can also be shared easily with Vishay FAEs for additional technical support or any other related question.

Flaunting high performance in a compact footprint, microBUCK serves as a cost-effective solution for point-of-load (POL) applications having input voltages from 2.7-36V and handling up to 15A of load current. The PowerCAD Simulation tool provides on-the-fly simulation for all of the following microBUCK devices: SiC413, SiC414, SiC424, SiC401, SiC402, SiC403 and SiP12107.
