Abstract
Power management techniques are disclosed. For instance, an apparatus may include a bidirectional voltage converter circuit, and a control module that selectively operates the bidirectional voltage converter circuit in a charging mode and a delivery mode. The charging mode converts a voltage provided by an interface (e.g., a USB interface) into a charging voltage employed by an energy storage module (e.g., a rechargeable battery). Conversely, the delivery mode converts a voltage provided by the energy storage module into a voltage employed by the interface. Other embodiments are described and claimed.
Claims26
(canceled)
An apparatus, comprising:
- a bidirectional voltage converter circuit comprising a charging mode and a delivery mode;
- an interface to couple the bidirectional voltage converter circuit to an attached device;
- and
- a control module to select the charging mode or the delivery mode for the bidirectional voltage converter circuit based on the attached device.
A method, comprising:
- selecting a charging mode or a delivery mode for a bidirectional voltage converter circuit with a control module, the control module to select the charging mode or the delivery mode based on an attached device coupled to the bidirectional voltage converter circuit via an interface.
A system, comprising:
- a bidirectional voltage converter circuit comprising a charging mode and a delivery mode;
- an interface coupled to the bidirectional voltage converter circuit;
- an attached device coupled to the bidirectional voltage converter circuit via the interface;
- and
- a control module to select the charging mode or the delivery mode for the bidirectional voltage converter circuit based on the attached device.
