摘要： A voltage converter includes a compensation unit, first and second control units, and an output voltage generation unit. The compensation unit selects compensation feedback voltage or output feedback voltage depending on an operation mode, and generates a compensation voltage based on the selected feedback voltage and a first reference voltage, the compensation feedback voltage corresponding to the compensation voltage, and the output feedback voltage corresponding to an output power supply voltage. The first control unit generates a first control signal based on the compensation voltage and a second reference voltage. The second control unit generates a second control signal based on the first reference voltage and the output feedback voltage. The output voltage generation unit selects one of the first control signal and the second control signal depending on the operation mode, and generates the output power supply voltage based on the selected control signal and an input voltage.
