摘要： A voltage regulator (Fig. 1), for supplying a high current load and a low current load, employs a feedback loop to supply the low current load with a fine degree of regulation and a feed forward arrangement to supply the high current load with a coarse degree of regulation. The feedback loop employs a bandgap reference source (13) feeding a comparator (17), with an output driver transistor (21) drawing current from a common supply (Vcc_ext) and having an output electrode (Vcc- int) connected to a voltage divider (31, 33), allowing a sample of the output to be fed back (39) to the comparator to maintain the desired output voltage. The output electrode also feeds (35, 45) a control transistor (47) for the feed forward arrangement that also draws current from the common supply and supplies the high current load directly.

摘要： A blank (10) formed from electrically conductive sheet material defines a continuous conductive path (12) which includes two terminal ends (14, 16) and at least three loops (18-24) disposed along the path (12). The blank (10) is foldable at preselected folding locations (36-50) on the path (12) with the loops (18-24) in overlying relation to one another, and the blank (10) is preferably formed with the loops (18-24) disposed along the conductive path (12) in substantially the same plane. The blank (10) is used to form a multi-turn planar winding (51) for a magnetic device (84) such as, for example, an inductor or transformer which may be incorporated into electrical circuits such as power supplies. The planar magnetic device (84) provides a low overall volume and profile, as well as a substantially higher volume or surface area of conductive material per turn of the winding (51) compared to conventional wire or etched windings to provide a higher current carrying capacity and fewer turns compared to conventional winding.

摘要： The present invention relates to an information processing apparatus that comprises a plurality of electric circuits and that has power supply lines for the individual electric circuits. It provides a switching regulator that controls the power that is supplied by an external power source to such an information processing apparatus, while inhibiting power waste, and the information processing apparatus and a method for its control.
The information processing apparatus, which is activated by power supplied from an external power source, comprises: a first power supply line for supplying power to a first electric circuitry; a second power supply line for supplying power to a second electric circuitry; a i-th power supply line for supplying power to a i-th electric circuitry (i is an integer of 1 ≦ i ≦ n, and n is an integer equal to 2 or greater); means for monitoring a first voltage of the first power supply line; means for monitoring a second voltage of the second power supply line; means for monitoring a i-th voltage of the i-th power supply line; means for selecting the minimum voltage among the first through the i-th voltages; means for comparing the minimum voltage with a previously given reference voltage; and connecting/disconnecting means for starting or halting the power supply from the external power source in response to the comparison result. As the lowest voltage can be used as a feedback target, the application of a high voltage is not required even if the safety of the system is taken into consideration and power will not be wasted.

摘要： The invention relates to a method to reduce the power consumption of an electronic device comprising at least one voltage regulator. At least one of the regulators (REG1 - REG4) is switched off and on according to a predetermined duty cycle during such periods when the electronic device does not require the normal power supply ability of the regulator. This may be realized e.g. in a mobile phone during two successive control channel messages received from a base station when the mobile phone is in a so called power saving mode.
