  • Multi-phase switching converters and methods
    Patent number: 6362608
    Abstract: Multi-phase switching converters and methods that provide fast response and low ripple on the converter inputs and outputs. The converters include multiple converter stages that are normally operated in sequence into a common load. However upon sensing that operation of one of the converter stages does not bring the converter back into regulation, multiple converter stages are operated until regulation is reestablished, after which the converter stages are operated in sequence again. In the embodiment disclosed, upon sensing that operation of one of the converter stages does not bring the converter back into regulation, all converter stages are operated until regulation is reestablished, after which the converter stages are operated in sequence again starting with the stage with the lowest inductor current.

  • Methods and apparatus to predictably change the output voltage of regulators
    Patent number: 6208127
    Abstract: Programmable voltage regulators that change from a first set-point voltage to a second set-point voltage at a controlled rate. The set-point signal is a multi-bit set-point signal with the rate of change in the regulator output between set-points being predetermined or externally controllable. Various embodiments are disclosed.
