Texas Instruments Inc. (TI) has launched a 10A 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 1MHz 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-mode 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.
The device's input voltage rating of 3V to 14V and output voltage range of 0.75V to 5.5V allows for flexible design in 3.3V, 5V and 12V power systems and can power various components, such as DSPs, FPGAs, ASICs, I/O and DDR memory cores.
Its adaptive on-time D-CAP Mode control scheme allows less than 0.1µs response time in load step transient with fewer components. The TPS51315 is available in a 40-pin 5x7mm QFN package.
