1. An apparatus comprising:
a direct current (DC) to DC converter, wherein the DC to DC converter comprises:
a plurality of input terminals comprising:
a first input terminal; and
a second input terminal;
an negative output terminal; and
a plurality of switches comprising:
a first switch connected to the first input terminal;
a second switch connected to the first switch and the output terminal;
a third switch connected to the second input terminal; and
a fourth switch connected to the third switch and the output terminal,
wherein the DC to DC converter is configurable to switch between operating in an upside-up buck mode of operation and in an upside-down buck mode of operation,
wherein, in the upside-up buck mode of operation, the third switch and the fourth switch are controlled to be on to connect the second input terminal of the DC to DC converter to the output terminal of the DC to DC converter, and the second input terminal of the DC to DC converter has substantially a same voltage as the output terminal of the DC to DC converter, and
wherein, in the upside-down buck mode of operation, the first switch and the second switch are controlled to be on to connect the first input terminal of the DC to DC converter to the output terminal of the DC to DC converter, and the first input terminal of the DC to DC converter has substantially the same voltage as the output terminal of the DC to DC converter.
