The WEBENCH System Power Architect has been designed to enable users to build and optimise 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, it adds the ability to accommodate multiple intermediate bus architectures and safety isolation in conjunction with TI’s hot-swap controllers and isolated power products.
TI’s WEBENCH tools have been used to create two million analogue designs since its introduction by National Semiconductor in 1999. With the addition of WEBENCH System Power Architect, designers will now be able to create isolated power systems with hot swap capability in about 60 seconds. When driving multiple loads, the designer can customise 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.
Key features of the WEBENCH System Power Architect include: 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; offers all of the capabilities of the existing WEBENCH FPGA and Processor Power Architects, supporting 268 processors and 190 FPGAs from seven suppliers and is able to support a variety of power supply topologies, including buck, boost, buck-boost, SEPIC, inverting, flyback and LDO.
