Texas Instruments TPS51315: 10A synchronous buck converter has integrated FETs
August 28, 2009
Combining a 10A synchronous buck converter with integrated FETs, the 1-MHz TPS51315 dc/dc switcher uses a D-Cap Mode control scheme, allowing fast transient response and reducing the required number of external output capacitors by 32%. The converter meets Energy Star/90 Plus guidelines using an auto-skip mode and an Eco-mode light-load-control scheme, achieving an improved efficiency across the entire load range. Additional features include a 3 to 14V input voltage, and a 0.75 to 5.5V output-voltage range enables flexible design in 3.3, 5, and 12V power systems. Available in a 5×7-mm QFN package, the TPS51315 dc/dc switcher costs $3.80 (1000).
