摘要： Disclosed is a power supply switching circuit comprising: a first switch pair for selectively connecting a first power supply node to an output node, a second switch pair for selectively connecting a second power supply node to the output node; and a switch control circuit. The switch control circuit is operable such that a first switch of each of said first switch pair and said second switch pair is controlled by a respective first control signal and a second switch of each of said first switch pair and the second switch pair is controlled by a respective second control signal, so as to connect no more than one of the first power supply node or the second power supply node to the output node at any one time.

摘要： Disclosed are control circuits for a SIMO voltage regulator, and associated voltage regulators. The control circuit comprises output switches for selective connection of each output to a first inductor terminal; and a controller. In an embodiment, the controller such that each output is periodically connected to the first inductor terminal for a respective connected time duration which are each dependent on at least one historical voltage value sampled in an earlier switching period on at least one of the outputs. In another embodiment, the output for which at least a first portion of its corresponding connected time duration is first calculated is periodically switched. In yet another embodiment, it is determined whether the SIMO is in a locked condition; whether the locked condition is valid; and if invalid, a respective alternative voltage regulator is used to supply one or more of the outputs.
