ABSTRACT:
A DC-DC converter control circuit can maintain a relationship of voltages established among the output voltages even when the output voltages of DC-DC converters are independently controlled. A first reference voltage with which a high-potential back-gate voltage is controlled and a second reference voltage with which a supply voltage is controlled are dynamically controlled to be varied independently from one another. A supply voltage is applied to the inverting input terminal of a second differential-input amplifier. The second reference voltage is applied to the first non-inverting input terminal of the second differential-input amplifier, and the first reference voltage is applied to the second non-inverting input terminal thereof. The second differential-input amplifier amplifies the difference between a lower one of the first and second reference voltages applied to the two non-inverting input terminals thereof and the supply voltage applied to the inverting input terminal thereof.
