Abstract:
A voltage regulation system comprising:a first power switch for regulating current input into said voltage regulation system; an inductor for providing an inductor current to a plurality of voltage outputs, said plurality of voltage outputs comprising at least one of a first voltage output and a second voltage output; a first switch for regulating said inductor current flow to said first voltage output; a second switch for regulating said inductor current flow to said second voltage output, a reference voltage; a first voltage error amplifier coupled to said voltage reference, said first voltage error amplifier for comparing said first voltage output to said voltage reference and providing a first error signal; a second voltage error amplifier coupled to said voltage reference, said second voltage error amplifier for comparing said second voltage output to said voltage reference and providing a second error signal; and a decision logic block for receiving at least one of said inductor current, said first error signal and said second error signal and providing a control signal to at least one of said first power switch, said first switch and said second switch for controlling the operational states of at least one of said first power switch, said first switch and said second switch.
