Abstract
Apparatuses and methods for providing output power are disclosed. In an example method, a control signal is received at an output stage. The control signal may be provided by a control circuit. The method further includes providing a first power to a filter responsive to the received control signal having a first value, and providing a second power to the filter responsive to the received control signal having a second value. The method further includes decoupling the first power and second power from the filter responsive to the received control signal having a third value
Claims27
An apparatus comprising:
- a control circuit configured to receive an enable signal and provide a control signal, a value of the control signal based on the enable signal;
- a high side circuit configured to receive first power at a first input and second power at a second input, the high side circuit further configured to selectively provide the first and/or second power to a node based on the value of the control signal;
- a low side circuit configured to selectively provide a reference to the node based on the enable signal;
- and
- a filter coupled to the node and configured to provide output power based on input received at the node.
An apparatus comprising:
- a power regulator circuit comprising:
- a control circuit configured to receive an enable signal and provide a control signal based on the enable signal;
- a high side switching circuit configured to receive first power at a first input and second power at a second input, the high side switching circuit further configured to selectively provide the first and/or second power to a node based on the control signal;
- a low side switching circuit configured to selectively provide a reference to the node based on the enable signal;
- a filter coupled to the node and configured to provide output power based on input received at the node;
- and
- a device circuit coupled to the power regulator circuit and configured to receive the output power.
An apparatus comprising:
- a high-side circuit comprising:
- a high side control input configured to receive a control signal from a control circuit;
- a plurality of power source inputs, each of the plurality of power source inputs coupled to a respective power source;
- and
- an output coupled to a filter input node, the output configured to provide at least one of the plurality of power sources to the filter input node based on a value of the control signal;
- a low-side circuit comprising:
- a low side control input coupled to a voltage controller,
- a low side input coupled to a ground terminal;
- and
- an output coupled to the filter input node.
A method comprising:
- receiving a control signal at an output stage, wherein the control signal is provided by a control circuit;
- providing a first power to a filter responsive to the received control signal having a first value;
- providing a second power to the filter responsive to the received control signal having a second value;
- and
- decoupling the first power and the second power from the filter responsive to the received control signal having a third value.
