Texas Instruments  XPS63802DLAT

The TPS63802 is a high efficiency, high output current buck-boostconverter. It is used when the input voltage is higher, equal, or lower than the output voltage.Output currents up to 2 A are supported over a wide voltage range. The device limits the peakcurrent at 4.5 A in Boost-Mode and 3.5 A in Buck-Mode. The device is adjusted to the programmedoutput voltage. It automatically changes from buck to boost operation based on the input voltage.It remains in a 3-cycle buck-boost mode when the input voltage is approximately equal to the outputvoltage. The transitions happen seamlessly and avoids unwanted toggling within the modes. TheTPS63802 comes in a 2 mm x 3 mm package. The device works with tiny passive components tokeep the overall solution size small.
