National Semiconductor's WEBENCH Visualizer

National Semiconductor's WEBENCH Visualizer

WEBENCHA(R) Visualizer is a powerful comparison and selection tool that enables engineers to rapidly select an optimal power system design from a large array of possibilities. It creates a graphical snapshot of options across multiple criteria, such as efficiency, footprint and system bill of materials (BOM) cost. Drawing from 25 different switching power supply architectures and 21,000 components, engineers can navigate through billions of power supply design alternatives in seconds. Design criteria can be modified and the real-time effects observed, allowing engineers to select the best DC-DC power supply based on their unique needs. The tool supports a variety of power supply topologies such as buck, boost, buck-boost, SEPIC and flyback. WEBENCH Visualizer gives design engineers all of the tools to produce the best possible design in the shortest time. Instead of a hard coded parametric table, this tool dynamically calculates key power supply parameters for 70 or more designs scenarios based on the user's inputs. The results are presented in a three-dimensional graph which makes it easy for the designer to drive to the desired solution, shaving days off of the power supply design time compared to doing calculations for designs one at a time.
