Abstract:
Disclosed is a circuit for controlling a single-inductor multiple-output voltage regulator. The voltage regulator includes the single inductor and is configured to generate an independent regulated voltage at each of a plurality of outputs. The circuit includes: a plurality of output switches configured to selectively respectively connect each of the plurality of outputs to a first inductor terminal of the inductor; and a controller configured to control the plurality of output switches in a plurality of switching periods such that, in an operational state, each of the plurality of outputs is periodically connected to the first inductor terminal for a respective connected time duration to generate the regulated voltage at a corresponding output.
