Texas Instruments TPS63060DSCT, 1 Buck Boost Switching, Buck/Boost Converter 1A, 2.5 → 8 V, 2600 kHz 10-Pin, WSON

Step-Down/Step-Up DC/DC Converters (Integrated Switch), Texas Instruments. This highly efficient buck-boost converter uses a single inductor for DC to DC conversion. With automatic transmission between its Step Down and Step Up functions, buck-boost converters can be employed in battery powered products that use either a two-cell and three-cell alkaline battery, a NiCd or NiMH, or a single cell Lithium battery. This makes it ideal for use with cellular phones and similar hand-held devices.
