Abstract
A power management device is disclosed, including a first DC-DC converter coupled to a first output voltage line and a second output voltage line, a second DC-DC converter coupled to the second output voltage line and a third output voltage line, a first set of switches associated with the first DC-DC converter, and a second set of switches associated with the second DC-DC converter. The power management device may further include a controller configured to toggle one or more switches of the first set of switches and one or more switches of the second set of switches, and a multi-mode radio-frequency front-end block communicatively coupled to the controller.

A power management device, comprising:
- a first DC-DC converter coupled to a first output voltage line and a second output voltage line;
- a second DC-DC converter coupled to the first output voltage line, the second output voltage line and a third output voltage line;
- a first set of switches associated with the first DC-DC converter;
- and
- a second set of switches associated with the second DC-DC converter;
- a third set of switches coupled to the first output voltage line and the second output voltage line;
- and
- a controller configured to toggle one or more switches of the first set of switches, one or more switches of the second set of switches, and one or more switches of the third set of switches to implement one or more power output modes, including a high-band high power user equipment power output mode in which the first DC-DC converter and the second DC-DC converter combine in parallel to each supply power to both the first output voltage line and the second output voltage line concurrently.
A packaged module for processing a signal, comprising:
- a packaging substrate configured to receive a plurality of components;
- a first DC-DC converter with a first set of switches;
- a second DC-DC converter with a second set of switches;
- a third set of switches configured to couple an output of the first DC-DC converter to an output of the second DC-DC converter;
- and
- a controller configured to toggle one or more switches of the first set of switches, toggle one or more switches of the second set of switches, and toggle one or more switches of the third set of switches to implement one or more power output modes, including a high-band high power user equipment power output mode in which the first DC-DC converter and the second DC-DC converter are each active on both a first output voltage line and a second output voltage line and the first DC-DC converter and the second DC-DC converter combine in parallel to each supply power to both the first output voltage line and the second output voltage line concurrently, the second DC-DC converter operating out of phase from the first DC-DC converter.
A wireless device comprising:
- an antenna configured to receive a signal;
- an amplifier assembly in communication with the antenna and configured to amplify the signal;
- a power management device comprising a first DC-DC converter coupled to a first output voltage line and a second output voltage line, a second DC-DC converter coupled to the first output voltage line, the second output voltage line, and a third output voltage line, a first set of switches associated with the first DC-DC converter, a second set of switches associated with the second DC-DC converter, and a third set of switches configured to activate the first DC-DC converter and the second DC-DC converter on two output lines of the first output voltage line, the second output voltage line, and the third output voltage line concurrently, to implement one or more power output modes, including a high-band high power user equipment power output mode in which to provide a combined output voltage from the first DC-DC converter and the second DC-DC converter in parallel to the two output lines of the first output voltage line, the second output voltage line, and the third output voltage line concurrently;
- and
- a transceiver in communication with the amplifier assembly and the power management device and configured to process the amplified signal.
