Abstract
A power management device is disclosed, including a first DC-DC converter coupled to a first output voltage line, a second DC-DC converter coupled to a second 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.
