Abstract
In accordance with embodiments of the present disclosure, a controller for controlling at least one switch of a switching converter may include a current estimator configured to determine an estimated inductor current through an inductor of the switching converter based on a previous sample of a current through the inductor and a switch control configured to control activation and deactivation of the at least one switch based on the estimated inductor current.
Claims16
A controller for controlling at least one switch of a switching converter, the controller comprising:
- a current estimator configured to determine an estimated inductor current through an inductor of the switching converter based on a previous sample of a current through the inductor;
- and
- a switch control configured to control activation and deactivation of the at least one switch based on the estimated inductor current.
A method, comprising:
- determining an estimated inductor current through an inductor of a switching converter based on a previous sample of a current through the inductor;
- and
- controlling activation and deactivation of at least one switch based on the estimated inductor current.
A circuit comprising:
- a switching converter;
- a switched output stage coupled to the switching converter, wherein the switching converter generates a supply voltage to the switched output stage;
- and
- a controller for controlling at least one switch of a switching converter, the controller comprising:
- a current estimator configured to determine an estimated inductor current through an inductor of the switching converter based on a previous sample of a current through the inductor;
- and
- a switch control configured to control activation and deactivation of the at least one switch based on the estimated inductor current.
