  • Switching power supply controller with high frequency current balance
    Patent number: 7965068
    Abstract: A controller for a multi-phase switching power supply shuffles the sequence of the phases in response to a load transient to prevent synchronization of one or more phases with high-frequency load transients. The sequence may be shuffled by varying the frequency and/or sequence of the switching control signals to introduce a random variation in the phases.
    Type: Grant
    Filed: November 19, 2010
    Date of Patent: June 21, 2011
    Assignee: Semiconductor Components Industries, LLC
    Inventors: David A. Tobin, Xiaogang Feng, Tod F. Schiff
