Abstract:
A voltage converter for converting a first voltage to an output voltage having a lower voltage than the first voltage, the voltage converter, comprising:an input node to which a first voltage is provided; an output node at which an output voltage having a lower voltage than the first voltage is provided; a voltage reduction circuit interposed between the input and output nodes and having a control node to which a control signal is applied, the voltage reduction circuit reducing the voltage of the first voltage according to the voltage of the control signal to provide the output voltage at the output node; and a feedback circuit having first and second inputs coupled to the input and output nodes, respectively, and further having an output coupled to the control node of the voltage reduction circuit, the feedback circuit coupling the input node to the control terminal in response to the voltage of the output voltage decreasing in excess of a voltage difference to compensate for the decrease in the output voltage.
