摘要： 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.

摘要： This invention aims at providing a control circuit of power supply in which a secondary battery and a device are connected in parallel, to output capable of preventing over-charging of the secondary battery and supplying power from the secondary battery to the device, and a control method of the power supply. A device 5G and a secondary battery 2G are connected to a DC-DC converter 1G in parallel. The device 5G is supplied with both a power from the DC-DC converter 1G and a power from the secondary battery 2G. When the secondary battery 2G is in non-charging state, an offset circuit 15G supplies a positive offset for reducing a difference of voltage between a detection signal Vx1G and reference voltage e1G to a reference voltage e1G corresponding to a charging inhibit signal CAS. An error amplifier ERA1G reduces an actually flowing charging current CCG by an amount corresponding to the offset value as a result of recognizing that the charging current CCG flows more by the amount corresponding to the offset value.
