Abstract:
1. A power supply to deliver a voltage across first and second supply terminals, the power supply comprising: a charge-storage device having first and second charge-storage terminals; an inductor having first and second inductor terminals; a buck switch having a first current-handling terminal coupled to the first charge-storage terminal, a second current-handling terminal coupled to the first inductor terminal, and a buck-switch control port; a boost switch having a third current-handling terminal coupled to the first inductor terminal, a fourth current-handling terminal coupled to the second charge-storage terminal and the second supply terminal, and a boost-switch control port; and a recharge-limit switch having a fifth current-handling terminal coupled to the second inductor terminal, a sixth current-handling terminal coupled to the first supply terminal, and a recharge-limit control port.
