Abstract
Circuit techniques control multiple regulator circuits. Regulator circuits are configured to time share voltage control circuitry. The voltage control circuitry may include multiple sets of switches to selectively couple a voltage control circuit with a selected voltage regulation loop of one of the regulators.
