Abstract
A voltage regulator coupled to an unregulated DC input voltage source by an input terminal, and to a load by an output terminal is disclosed. The voltage regulator converts an input voltage at the input terminal to an output voltage at the output terminal. The voltage regulator includes one or more slaves, and each slave includes a switching circuit which serves as a power switch for alternately coupling and decoupling the input terminal to an intermediate node. Each slave can include a high-side power transistor having a drain connected to the input terminal and a source connected to the intermediate node, and a low-side power transistor having a source connected to ground and a drain connected to the intermediate node. Each slave can act as a switching circuit to alternate between coupling the intermediate node to the input terminal and between the intermediate node to a ground.
