  • Patent number: 6262566
    Abstract: A DC-to-DC regulator that includes a multi-phase synchronous buck regulator having a pulse width modulator to generate a plurality of switching signals, a plurality of drivers, each coupled to receive one of the switching signals, and a plurality of switching voltage converters, each coupled to receive an output from one of the drivers and an input voltage, wherein the outputs of the switching voltage converters are combined to form an output voltage. The multi-phase synchronous buck regulator can be implemented on a motherboard, such as on an interposer board or directly on a PU chip.

  • Patent number: 6212086
    Abstract: Briefly, in accordance with one embodiment of the invention, a DC-to-DC converter package includes: a DC-to-DC converter circuit. The components of the DC-to-DC converter circuit that perform high frequency switching during converter operation are surface mounted on a printed circuit board (PCB) so that the heat produced from the high frequency switching is approximately equally distributed at least over the portion of the PCB where the components are mounted.

  • Patent number: 6018468
    Abstract: A DC-to-DC converter, comprising: inverter means for receiving a DC input and providing as an output a high-frequency, alternately pulsed current waveform; a control winding for receiving the output of the inverter means, the control winding being wound on a common bobbin with first and second tank windings, the windings de-coupled on the bobbin so that there is a significant leakage inductance between the windings, the first and second tank windings having two discrete resonant frequencies on a common core and flux path, a main primary winding wound in series with the control winding, the main primary winding being wound onto a separate bobbin and residing on its own core leg and flux path, first and second secondary windings coupled with the main primary winding, the first and second secondary windings being wound out of phase with each other, the first and second secondary windings feeding, respectively, first and second diodes, the first and second diodes rectifying the alternately pulse current waveform

  • Patent number: 5574667
    Abstract: A computer system has control circuitry for detecting directly and independently of temperature the malfunctioning of a fan used for cooling the housing of the computer and for controlling the power supply voltage when malfunctions are detected so as to reduce the temperature within the housing of the computer system.

  • Patent number: 5526289
    Abstract: A personal computer has at least one heat producing element within its housing with a fan for cooling the inside of the housing. The fan is controlled by a temperature dependent fan control circuit. A heat sensing device within the fan control circuit adjusts the voltage applied to the fan in a substantially continuous relationship to the temperature inside the housing.

  • Patent number: 5455757
    Abstract: A power converter including a complementary regeneration circuit for eliminating oscillations and conserving leakage energy to increase the efficiency of a flyback power converter. The complementary regeneration circuit includes a regeneration capacitor, a regeneration switch, a diode and appropriate timing circuitry to switch the regeneration capacitor in and out of the circuit at the appropriate times. Due to the operation of the regeneration switch, the capacitance of the regeneration capacitor is much larger than a typical snubber/clamp capacitor, so that it overdamps the circuit eliminating voltage overshoot typically appearing across the primary switch. The regeneration capacitor charges with regeneration energy and drives negative current into the primary inductor, holding the voltage across the primary switch constant when the secondary current goes to zero.
