Abstract
DC/DC converters using dynamically adjusted variable size switches are described herein. In one embodiment, a power switch includes multiple switching elements coupled to each other, each of the switching elements independently switching to convert an input voltage to an output voltage of a DC/DC converter, and a duty cycle of the DC/DC converter being determined based on a duty cycle of each of the switching elements. Other methods and apparatuses are also described.
Claims38
A power switching circuit, comprising:
- a plurality of switching elements coupled to each other, each of the switching elements independently switching to convert an input voltage to an output voltage of a DC/DC converter, and a duty cycle of the DC/DC converter being determined based on a duty cycle of each of the switching elements.
A DC/DC converter, comprising:
- an input circuit to receive an input voltage;
- an output circuit to provide an output voltage;
- and
- a power switching circuit coupled to the input and output circuits to convert the input voltage to the output voltage, the power switching circuit including
- a plurality of switching elements coupled to each other, each of the switching elements independently switching, and a duty cycle of the DC/DC converter being determined based on a duty cycle of each of the switching elements.
A data processing system, comprising:
- a bus;
- a processor coupled to the bus;
- one or more devices coupled to the bus;
- and
- a DC/DC converter to provide a supply voltage to at least one of the processor and the one or more devices, the DC/DC converter including
- an input circuit to receive an input voltage,
- an output circuit to provide an output voltage, and
- a power switching circuit coupled to the input and output circuits to convert the input voltage to the output voltage, the power switching circuit including
- a plurality of switching elements coupled to each other, each of the switching elements independently switching, and a duty cycle of the DC/DC converter being determined based on a duty cycle of each of the switching elements.
A method, comprising:
- generating a plurality of control signals;
- and
- independently controlling a plurality of switching elements of a power switching circuit of a DC/DC converter using the plurality of control signals to convert an input voltage to an output voltage of the DC/DC converter, a duty cycle of the DC/DC converter being determined based on a duty cycle of each of the switching elements.
