OUTPUT VOLTAGE ADAPTIVE VOLTAGE CONVERTING APPARATUS AND METHOD THEREOF

摘要

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 (V OB ) 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).
