摘要： A step-up power supply unit for providing a multiplicity of different step-up voltages as needed, generated by stepping up a voltage of a single power source such as a battery.

摘要： According to the invention, as an input voltage of a certain step-up unit of a plurality of stages of step-up units, a stepped-up output of a step-up unit in a stage preceding the certain step-up unit is inputted. This makes it possible to increase the level of a voltage stepped up by each step-up unit, and reduce the number of units. Furthermore, according to the invention, when an output voltage of a step-up unit that performs stepping-up operation according to a reference constant current is lower than a reference voltage, a reference constant current is produced; when the output voltage thereof exceeds the reference voltage, the reference constant current is stopped. This makes it possible to provide stable output of an output voltage at a predetermined level, and reduce an inrush current during start-up to a predetermined current level.

摘要： According to the invention, a charge pump circuit (21) has, as switching means turned on when a capacitor (C1) is charged, transistors (P1 to P3) connected in parallel between one end of the capacitor (C1) and an input terminal (T1). When the capacitor (C1) is charged, a controller (CNT) determines which of the transistors (P1 to P3) to drive based on the results of monitoring of the input and output voltages by first and second detectors (DET1, DET2). Thus, even if the level of the input voltage varies, it is possible to reduce in-rush current at start-up without causing a drop in the output voltage or a loss in efficiency.
