  • Output voltage adaptive voltage converting apparatus and method thereof
    Patent number: 7812588
    Abstract: The present invention is related to, in general, an output voltage adaptive converting apparatus and method thereof. The invention provides an output voltage adaptive voltage converting apparatus, comprising a clock generating unit that generates predetermined clock signals; a switching amplifying unit that amplifies an input voltage (Vi) and produces an output voltage (Vo) based on the clock signals; a feedback filtering unit that filters the output voltage (Vo) and produces a filtered voltage (VOB); a voltage comparing unit that compares the filtered voltage (VOB) with the input voltage (Vi) and produces a control voltage (Vc); and a voltage switching unit that connects a source voltage (Vdd) of the clock generating unit to the input voltage (Vi) or the filtered voltage (VOB) based on the control voltage (Vc).
    Type: Grant
