Abstract: Power supplies combining a switching-mode power supply in parallel with a current source can improve maximum load current capability. The current source can be turned on, or the amount of current supplied by the current source increased, when there is a heavy load current demand, for example, when the load current demand is more than the current rating of the switching-mode power supply. The duty cycle of the output stage of the switching-mode power supply can be used to determine the load current demand. The current source may increase the maximum output current of the power supply beyond the maximum output current of the switching-mode power supply. For example, the current source may add 0.5 A to the current capability of a 2.5 A switching-mode power supply.

Abstract: Methods, apparatuses, and systems may provide for regulating the system voltage in a mobile device by utilizing a bypass switch as a linear control circuit. A second switch is connected an output of a first switch and to a voltage control circuit. The linear control circuit detects a system voltage and compares the detected system voltage to a reference voltage. The linear control circuit will fully turn on the second switch when the system voltage is below the voltage threshold set by the reference voltage. However, when the system voltage exceeds the set voltage threshold, the second switch will automatically clamp the system voltage to remain at the voltage that is set by reference voltage.

Abstract: A power supply system uses a DC-DC power converter (28) for supplying an output load. A compensation circuit (40) is connected between the input to the DC-DC converter and the output of the DC-DC converter and it provides a compensating path in response to a voltage drop at the output of the DC-DC converter caused by a surge in the output load. The power supply system further comprises a low drop out regulator (30) as the output load, which low drop out regulator (30) having an input connected to the DC-DC power converter and the compensation circuit, and an output connected to an output terminal (C) for connection to a further output load. This enables the DC-DC power converter to have a low current capability, because a large current demand can be met by the DC supply to the DC-DC converter.
