  • Publication number: 20190006946
    Abstract: A switching regulator having adjustable inductor current threshold employs a control method which includes: (S1) determining whether an output voltage is greater than a reference voltage or determining whether a switching frequency of the power stage is smaller than a predetermined lower frequency limit, and (S2) when it is determined yes in the step (S1), adjusting the inductor current threshold, such that the switching regulator operates under a pseudo discontinuous conduction mode (PDCM) wherein the switching frequency is not smaller than the predetermined lower frequency limit. Consequently, when the switching regulator operates under a light load mode, an optimum balance between a total power consumption and switching noise interference will be ensured.

  • Publication number: 20130076635
    Abstract: A membrane touch keyboard structure for notebook computers comprises a panel, a sensing layer, a backlight layer and a base layer. The panel includes hot key patterns, a key group pattern, a cursor control pattern, and a sensing key pattern. A first sensing block, first electrode blocks, a second sensing block, a third electrode block or a third sensing block, and a fourth sensing block correspond to sensing layers of the hot key patterns, key group pattern, cursor control pattern, and sensing key pattern. The sensing layers are resistive/capacitive films. The membrane touch keyboard and the touch panel are integrated to reduce the thickness of the notebook computer. When any hot key pattern, key group pattern, cursor control pattern or sensing key pattern is touched, the touch is sensed by the sensing layer to generate and output a sensing control signal to the notebook computer for an operation.
