摘要： A booster type DC-DC conversion circuit and a voltage reduction type DC-DC conversion circuit are connected in series with a battery. When battery voltage is high, the booster type DC-DC conversion circuit does not operate, and the voltage reduction type DC-DC conversion circuit outputs a constant voltage lower than the battery voltage. When the battery voltage drops, the booster type DC-DC conversion circuit operates, and converts the battery voltage to a constant voltage higher than the operation voltage of the voltage reduction type DC-DC conversion circuit. The voltage reduction type DC-DC conversion circuit outputs a constant voltage. The power supply apparatus can continuously output a constant voltage from when the battery voltage is high until it becomes low, and can efficiently utilize the battery capacity.

摘要： The invention provides a DC-DC converter capable of being started up in a state in which an input voltage is low and capable of being structured without increasing a circuit size. A back-gate voltage (Vsb) is outputted from a back-gate voltage generating circuit (VBGN), and is inputted to a back gate of a transistor (FET1). During a period during which an output voltage (Vout) is lower than a reference voltage (e0), an oscillation signal (OS1) is inputted to a gate of the transistor (FET1), and the back-gate voltage (Vsb) is set at a grounded voltage. Therefore, the transistor (FET1) has a reference threshold voltage (Vto). On the other hand, during a period during which the output voltage (Vout) is higher than the reference voltage (e0), a pulse signal (PS) is inputted to the gate of the transistor (FET1), and the back-gate voltage (Vsb) is set at an output voltage of a charge pump portion (5). Therefore, the transistor (FET1) has a threshold voltage higher than the reference threshold voltage (Vto).

摘要： A DC-DC converter for generating a stable output voltage and being applicable to a transient load fluctuation. The DC-DC converter detects an input current, and compares the input current with a rated current of an external power supply. The DC-DC converter controls a positive charging current that is supplied to a secondary battery in accordance with a consumption current of a load so that the input current does not exceed the rated current. The DC-DC converter further controls a negative charging current that is supplied from the secondary battery to the load when the load requires an input current exceeding the rated current.

摘要： A reference voltage generating circuit generates a reference voltage Vref. An A/D converting circuit compares an analog input voltage Vin with the reference voltage Vref to convert the analog input voltage Vin to a digital output value Dout. A measured value storing circuit stores a measured value of the reference voltage Vref in advance and outputs the stored measured value. A user of an A/D converter corrects the digital output value Dout from the A/D converting circuit by use of the measured value of the reference voltage Vref outputted from the measured value storing circuit, thereby obtaining a digital value representing the analog input voltage Vin accurately irrespective of the accuracy of the reference voltage Vref.
