Texas Instruments has expanded its Webench suite of tools with Webench System Power Architect, an online tool to speed design of multi-output, high-performance dc/dc power supply systems.
Webench System Power Architect enables the user to build and optimize a complete power system from the edge of the card to the smallest point-of-load. In addition to the design and simulation of individual point-of-load converters, the tool adds the ability to accommodate multiple intermediate bus architectures and safety isolation in conjunction with TIís hot-swap controllers and isolated power products.
With the addition of Webench System Power Architect, designers can create isolated power systems with hot swap capability in just about 60 seconds, claims TI. When driving multiple loads, the designer can customize output voltages and load currents, and also select FPGAs and processors, which are preconfigured with critical requirements, load grouping and sequencing. Other options to select include ripple filter, low dropout regulators (LDO), external sync or separate supply.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for todayís commercial processor giants such as Intel, ARM and Imagination Technologies.
