Electronic device for switched DC-DC conversion having high-efficiency at high load and low load and method for operating the same

摘要

An electronic device for switched DC-DC conversion of an input voltage level into an output voltage level, comprising a first power switch and a second power switch, being connected in parallel and having a different gate width, and a driving stage that is configured to selectively drive the first power switch and/or second power switch depending on a load current output.
