National Semiconductor Corp. expanded its Webench Designer tools with the introduction of Webench Power Architect, which allows engineers to create, model and implement multiple-output, high-performance DC/DC power supplies for an entire system. According to the company, 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. Power Architect supports the company’s new Simple Switcher power modules, which offer integrated solutions for power supplies requiring low parts-count, small footprint, thermal resistant and low EMI. Using the tool’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 1 V to 100 V; up-to-20 system loads (VOUT) from 0.6 V – 300 V; power per load up to 300 W; system efficiency greater than 90 percent; and per-supply footprints from 14 mm x 14 mm.
