Texas Instruments’ new fully integrated 10-A synchronous buck converter with integrated FETs enables industry-leading power density

Texas Instruments Incorporated today introduced a fully integrated, 10-A synchronous buck converter with integrated FETs that combines wide input, light load efficiency and reduced solution size to enable increased power density. The TPS51315, a 1-MHz DC/DC switcher, features D-CAP™ Mode control scheme, which allows a fast transient response while reducing the required number of external output capacitors by 32 percent compared to competing devices. This converter helps designers meet Energy Star/90 Plus guidelines by utilizing auto-skip mode and Eco-modeTM light load control schemes to achieve high efficiency across the entire load range. Its wide input and output voltage ranges and programmable switching frequency can enable designers to meet the requirements of power-dense applications in embedded PCs, notebooks and other computing applications, as well as base stations and network attached storage.
