Industry's first online tool provides full system-level power design, including hot-swap control and isolated DC/DC conversion

Texas Instruments Incorporated has expanded the company's WEBENCH suite of tools by introducing WEBENCH System Power Architect, the industry's first 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, this innovative tool adds the ability to accommodate multiple intermediate bus architectures and safety isolation in conjunction with TI's hot-swap controllers and isolated power products.      

Engineers worldwide have used TI's WEBENCH tools to quickly create more than two million analog designs cost-free since its introduction by National Semiconductor in 1999. With the addition of WEBENCH System Power Architect, designers can create isolated power systems with hot swap capability in just about 60 seconds. 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.      

The WEBENCH System Power Architect includes a variety of hot swap controllers from TI, such as the LM5069 with power limiting, as well as isolated power products, such as the 10-W PTMA402050.     

The tool offers all of the capabilities of the existing WEBENCH FPGA and Processor Power Architects, supporting 268 processors and 190 FPGAs from seven suppliers.     

The tool also supports a variety of power supply topologies, including buck, boost, buck-boost, SEPIC, inverting, flyback and LDO.
