What is TPS63060DSCR?
The TPS63060DSCR is a high-input voltage buck-boost converter with a 2A switch current that provides a power supply solution for devices powered by alkaline, NiCd, or NiMH batteries, as well as one-cell or dual-cell Li-ion or Li-polymer batteries, When using a dual-cell Li-Ion or Li-polymer battery and discharging it to 5V or lower, output currents can reach 2A. To achieve maximum efficiency, the buck-boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller with synchronous rectification. The converter enters power-saving mode at low load currents to maintain high efficiency throughout a wide load current range.
The converter can be forced to operate at a fixed switching frequency if the power-saving option is disabled. The maximum average current in the switches is limited to a typical value of 2.25A. The output voltage is programmable using an external resistor divider or is fixed internally on the chip.

What is buck-boost converter?
A buck-boost converter (also known as a chopper) is a type of DC–to–DC converter with an output voltage magnitude that is either more than or less than the input voltage magnitude. It works in the same way that a transformer does in AC circuits: it "steps up" the DC voltage,
It's the same as a flyback converter, but instead of a transformer, it uses a single inductor. Buck-boost converters are two distinct topologies.
