Abstract
A switching regulator includes an inductive element to provide a first voltage across the element and at least one switch to energize and de-energize the inductive element to produce an output voltage. A controller of the regulator constructs an indication of a current from the first voltage and operates the switch(es) to regulate the output voltage in response to the indication.
Claims10
A voltage regulation system comprising:
- switching regulator circuits, each regulator circuit having an associated inductive element and providing a voltage across the associated inductive element;
- and
- a controller coupled to the switching regulator circuits to:
- cause the switching regulator circuits to operate at different switching phases,
- construct indications of currents from the voltages across the associated inductive elements, and
- control operations of the switching regulator circuits to regulate an output voltage of the system in response to the indications.
