    Abstract: A boost and LDO hybrid converter with dual-loop control is disclosed. In some implementations, a hybrid converter includes an inductor having a first terminal to receive an input voltage and a second terminal; an n-type metal oxide semiconductor device (nMOS) having a drain coupled to the second terminal of the inductor; a p-type metal oxide semiconductor device (pMOS) having a gate, a drain, and a source, the source coupled to the second terminal of the inductor; an output capacitor having a first terminal coupled to the drain of the first pMOS; and a controller having a switch driver and a buffer, wherein the controller is configured to use the switch driver to drive the gate of the first pMOS in a boost mode and to use the buffer to drive the gate of the first pMOS in a low drop out (LDO) mode.

    Abstract: Certain aspects of the present disclosure relate to methods and apparatus for Multiple Input Single Inductor Multiple Output (MISIMO) power conversion for power management circuits. Certain aspects provide a method for controlling a power conversion circuit. The method includes selectively opening and closing one of a first switch, second, and third switch to cause a terminal coupled to an output of the third switch to carry a signal at a first voltage based on one or more parameters associated with a first voltage source and one or more parameters associated with a second voltage source. The method further includes selectively opening and closing one of the first switch and the second switch and a fourth switch to cause a terminal coupled to an output of the fourth switch to carry a signal at a second voltage based on each of the one or more parameters.

    Abstract: A switchable supply network for powering multiple digital islands. In one embodiment, a first digital island includes a first power collapsible circuit and a first retention circuit, and a second digital island includes a second power collapsible circuit and a second retention circuit. In a normal mode of operation, the first digital island is provided a first supply voltage and a second digital island is provided a second supply voltage higher than the first supply voltage. In a transition mode the second power collapsible circuit is powered down and the second supply voltage is lowered and provided to the second retention circuit. When the second supply voltage falls below the first supply voltage, the first power collapsible circuit is powered down. The second supply voltage is now provided only to the retention circuits, and is furthered lowered in a retention mode to a final retention voltage.
