    Date of Patent: October 24, 2006
    Assignee: Semiconductor Components Industries, L.L.C.
    Inventor: Paul J. Harriman
  • Power supply controller and method
    Patent number: 7057381
    Abstract: In one embodiment, a power supply controller is configured to amplify a feedback signal and a voltage reference signal by gains that are substantially constant over an operating frequency of the power supply controller.

    Inventors: Paul J. Harriman, J. Eric Lindberg, Eric Reicher
  • Method of forming a transistor driver and structure therefor
    Patent number: 6982574
    Abstract: In one embodiment, a power supply system has a transistor driver that receives a PWM signal and generates signals to drive output transistors of the power supply system in response to the PWM signal. If the PWM signal is low for a certain length of time, the transistor driver disables t least one of the output transistors.

  • Battery backup unit system and interface
    Patent number: 6509657
    Abstract: A battery backup unit can be used to supply backup power to a computer. The battery backup unit includes a charge circuit that is connected to the computer's power supply unit. The charge circuit is also connected to a battery pack that includes a battery. The charge circuit converts an input high DC voltage signal supplied by the power supply unit to a charging signal. The charging signal can be used to charge the battery in the battery pack. The battery backup unit also includes a discharge circuit that is connected to the power supply unit and the battery pack. The discharge circuit converts a battery signal received from the battery pack to an output high DC voltage signal. The output high DC voltage signal can be fed into the power supply unit in order to drive the power supply unit if there is an indication that the AC power input to the power supply unit is inadequate to drive the computer.
