  • Publication number: 20090224602
    Abstract: There is provided a DC-DC converter control circuit, wherein a reference feedback signal related to a supply voltage to a load is compared to a reference oscillation signal to generate a result of comparison. The result of comparison is used as a switching control signal to control the supply voltage to the load. The result of comparison is frequency divided to generate a frequency divided signal; and the switching control signal is generated in response to the frequency divided signal.

  • Patent number: 7587266
    Abstract: A vehicle speed calculating section calculates the vehicle velocity by integration of a forward and reverse acceleration of a vehicle. A first deforming speed calculating section calculates a first deforming speed by integration of acceleration from a first acceleration sensor. A second deforming speed calculating section calculates a second deforming speed by integration of acceleration from a second acceleration sensor. A first deforming speed correcting section subtracts a vehicle speed from the first deforming speed and outputs it to a determining section. A second deforming speed correcting section subtracts the vehicle speed from the second deforming speed and outputs it to the determining section. In the determining section, the collision object determination is made on the basis of the corrected deforming speed.

  • Publication number: 20090003021
    Abstract: A chopper type DC-DC converter includes a voltage converting circuit, a comparative wave generating circuit, a comparator group, and a switch control circuit. The voltage converting circuit converts a first voltage into a second voltage. The comparative wave generating circuit generates first and second comparative waves such that the voltage range of the first comparative wave is different from the voltage range of the second comparative wave. The comparator group generates a first comparison result signal indicating a result of comparison between the first comparative wave and an error signal indicating an error between the second voltage and target voltage and a second comparison result signal indicating a result of comparison between the second comparative wave and the error signal. The switch control circuit controls the voltage converting circuit based on the first and second comparison signals. The comparative wave generating circuit includes first and second comparative wave generating circuits.
