Abstract:
1. A voltage regulator circuit comprising: at least first and second controllers at least first and second output stages; and a configuration matrix including a plurality of switches operable to selectively couple the first and second controllers to the first and second output stages or to selectively uncouple the first and second controllers from the first and second output stages; wherein said first controller is operable to receive a reference signal and a first feedback signal and to generate a first internal signal operative to cause a difference between the first feedback signal and the reference signal to be less than a first predefined value, said first feedback signal being representative of a first regulated output voltage, said second controller is operable to receive the reference signal and a second feedback signal and to generate a second internal signal operative to cause a difference between the second feedback signal and the reference signal to be less than a second predefined value, said second feedback signal being representative of a second regulated output voltage, wherein in response to a configuration data received by the configuration matrix the plurality of switches cause the first controller to be coupled to the first output stage and the second controller to be coupled to the second output stage, thereby causing:
