  • PHASE DOUBLING FOR SWITCHING POWER SUPPLY
    Publication number: 20140035543
    Abstract: A switching power supply control system may include logic to generate a greater number of second switching control signals in response to a first number of original switching control signals. For example, the logic may increase the number of phases that may be controlled by an existing switching power supply controller. The logic may be configured to steer feedback signals from the increased number of phases back to original feedback inputs on the controller.
    Type: Application
