Abstract
DC-DC voltage regulators for converting an input voltage into one or more output voltages and methods for operating such voltage regulators are described. The voltage regulator may have a high side switching device coupled between the input port and a first intermediate node. The voltage regulator may have an inductive element having one port coupled to the first intermediate node and may have a capacitive element having two ports, coupled between the first intermediate node and a second intermediate node, with its one port coupled to the first intermediate node. The voltage regulator may have a charging switching device coupled between the other port of the capacitive element and a predetermined voltage level, for charging the capacitive element when the high side switching device and the charging switching device are both in an ON state.
