Abstract
A single-inductor multi-output converter that includes a charge pump unit, a current supply unit, a first output unit, and a second output unit. The charge pump unit may be positioned between a first node and a second node, and may store electric charges flowing into the first node and the second node through a first capacitor, or may supply electric charges to the second node. In addition, the current supply unit may: include an inductor positioned between an input node and the first node; build up current in the inductor in the first time period; and transfer the current of the inductor to the charge pump unit in the second time period.
Claims10
A single-inductor multi-output converter comprising:
- a charge pump unit configured to be positioned between a first node and a second node, and configured to store electric charges flowing into the first node and the second node through a first capacitor or to supply electric charges to the second node;
- a current supply unit configured to include an inductor positioned between an input node and the first node, and configured to build up current in the inductor in the first time period and to transfer the current of the inductor to the charge pump unit in the second time period;
- a first output unit configured to include a second capacitor connected to a first output node, and configured to move electric charges from the second capacitor to the first capacitor in the first time period;
- and
- a second output unit configured to include a third capacitor connected to a second output node, and configured to move electric charges from the first capacitor to the third capacitor in the second time period.
A single-inductor multi-output converter comprising:
- an inductor configured to have one side connected to an input node and the other side connected to a first node;
- a first switch configured to have one side connected to the first node and the other side connected to a low-voltage portion;
- a first capacitor configured to have one side connected to the first node and the other side connected to a second node;
- a second capacitor configured to supply a first voltage to a first output node;
- a third capacitor configured to supply a second voltage to a second output node;
- a second switch configured to have one side connected to the second node and the other side connected to the second capacitor;
- and
- a third switch configured to have one side connected to the second node and the other side connected to the third capacitor.
