Selection tool enables comparison of power solutions
WEBENCH Visualizer is a comparison and selection tool that enables selection of optimal power devices in a system design. It creates a graphical snapshot of options across multiple criteria, such as power efficiency, footprint, and system bill-of-materials 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 unique needs.
The tool supports a variety of power supply topologies such as buck, boost, buck-boost, SEPIC and flyback. Several alternative circuit configurations are also available to address specific needs like fixed-frequency and constant-on-time architectures as well as current-mode and voltage-mode control loops. It offers a power parts library from 110 manufacturers and allows specification of VIN of 1 to 100 V, VOUT of 0.6 to 300 V, power up to 300 W, efficiency up to 96%, frequency up to 3 MHz, and a footprint of 14 x 14 mm. Once a design is selected, users can tune and optimize the design through additional component options and electrical and thermal simulation.
