Title:
CONTROL OF PARALLEL-CONNECTED VOLTAGE REGULATORS FOR SUPPLYING POWER TO INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO2006055557
Kind Code:
A3
Abstract:
An apparatus includes a first voltage regulator that is controlled to provide an output voltage that matches a reference voltage. The apparatus further includes a second voltage regulator that is coupled to an output of the first voltage regulator and controlled to minimize a current output from the first voltage regulator.
