SINGLE INDUCTOR MULTIPLE OUTPUT DC-DC CONVERTOR |
| 摘要 |
A single inductor multiple output (SIMO) DC-DC convertor is provided. The SIMO DC-DC convertor is configured to establish a first DC voltage at a first node and establish a second DC voltage at a second node. A first switch of the SIMO DC-DC convertor is activated when a voltage at the first node is below the first DC voltage. A second switch of the SIMO DC-DC convertor is activated when a voltage at the second node is below the second DC voltage. The first switch is deactivated when the voltage at the first node is not below the first DC voltage. The second switch is deactivated when the voltage at the second node is not below the second DC voltage. The first switch and the second switch, and other switches in the SIMO DC-DC converter, are activated in any order and independently of one another to establish desired node voltages. |

1. A single inductor multiple output (SIMO) DC-DC convertor configured to establish a first DC voltage at a first node and a second DC voltage at a second node, comprising:
an inductor; a first switch connected to a first side of the inductor and to the first node, the first switch configured to be activated when a voltage at the first node is below the first DC voltage; and a second switch connected to the first side of the inductor and to the second node, the second switch configured to be activated when a voltage at the second node is below the second DC voltage. |
