摘要： A power supply control method is adapted to a current-to-voltage conversion circuit which has a transformer for converting and outputting an input power. The power supply control method stops a power supply to the transformer when an output side of the current-to-voltage conversion circuit is in a no-load state, and starts a power supply to the transformer when an external voltage is applied to the output side of the current-to-voltage conversion circuit.

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： A DC-DC converter applicable to a wide input voltage range. An error amplifier compares a divided voltage, which is generated by dividing output voltage with a plurality of resistors, and a reference voltage to generate an error signal. A voltage source generates an offset signal by offsetting the error signal. A PWM comparator compares the offset signal with a triangular wave signal to generate a drive signal for controlling activation and inactivation of a first output transistor and a second transistor at a duty corresponding to the comparison result. An offset controller determines the ratio between the output voltage and the input voltage and controls the offset voltage of the voltage source in accordance with the determination.

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.
