Abstract
An electronic device includes a power management integrated circuit (PMIC) including a plurality of regulators. Each of the plurality of regulators has a current meter configured to measure a respective load current. A load device is configured to receive real-time load current information from the PMIC and to perform a performance improvement operation based on the real-time load current information.

An electronic device comprising:
- a power management integrated circuit (PMIC) including a plurality of regulators, each of the plurality of regulators having a current meter configured to measure a respective load current;
- and
- a load device configured to receive real-time load current information from the PMIC and to perform a performance improvement operation based on the real-time load current information.
11-18. (canceled)
A switching regulator to transform direct current (DC) input voltage with a switching method, the switching regulator comprising:
- an inductor configured to receive the DC input voltage at a first terminal;
- a first transistor configured to switch between a second terminal of the inductor and a ground voltage;
- a second transistor configured to switch between the second terminal of the inductor and an output terminal;
- and
- a current meter configured to sense a differential voltage of a drain-source node of the second transistor and to supply the sensed differential voltage as load current information.
23-32. (canceled)
The switching regulator of claim 24, wherein the first transistor and the second transistor are complementarily driven.
