National Semiconductor has expanded its WEBENCH Designer tools with the introduction of WEBENCH Power Architect - the industry’s first design tool that allows engineers to rapidly create, model and implement multiple-output, high-performance DC-DC power supplies for an entire system. With WEBENCH Power Architect, system designers can instantly optimize multiple power supplies across several performance parameters including topology, intermediate voltage rails, footprint, efficiency, component count and bill of materials (BOM) cost.

“WEBENCH Power Architect is the first tool to make it easy to quickly design power supplies for all of the loads in a system,” said Phil Gibson, vice president of Technical Sales Tools at National Semiconductor. “Depending on the tool’s optimizer dial setting, a typical system with eight power loads will have a BOM count ranging from 50 to 150 components. This is the only tool that lets you instantly compare performance and cost for many alternative system combinations, and quickly implement them.”

WEBENCH Power Architect supports National’s new SIMPLE SWITCHER® power modules, also announced today. They provide highly integrated and easy-to-use solutions for power supplies requiring low parts-count, small footprint, thermal resistant and low electromagnetic interference (EMI). Using WEBENCH Power Architect’s library of 21,000 components from 110 manufacturers, designers have a wide range of system alternatives for creating large scale complex systems:

• System input sources (VIN) from 1V – 100V

• Up-to-20 system loads (VOUT) from 0.6V – 300V

• Power per load up to 300W

• System efficiency greater than 90 percent

• Per-supply footprints from 14 mm by 14 mm
