The TPS51315 is a D-CAPTM Mode, 10-A, synchronous step-down converter with integrated MOSFETs. The combination of D-CAPTM mode and on-board MOSFETs provides fast transient response performance with ease of use, less external component count and small footprint. Externally adjustable switching frequency allows optimal design between component size and efficiency tradeoff. Ceramic output capacitors can be employed by adding a few extra components. The TPS51315 is available in the thermally-efficient 40-pin, 5 mm x 7 mm, QFN package and is specified from -40C to 85C ambient.
