ABSTRACT:
An N-channel MOS transistor is used to configure a DC—DC converter having good characteristics without providing a particular voltage circuit which outputs a voltage higher than an input voltage. An N-channel MOS transistor11and a choke coil12are connected in series between a negative side of a direct-current power supply and a negative side of the output capacitor8. A PWM circuit14applies pulse signals to a gate of the MOS transistor11based on the input voltage divided by the capacitors9and10. The pulse signal of the PWM circuit14is formed by the voltage corresponding to the output voltage of the output capacitor8, and the pulse signal is inputted to the gate of the N-channel MOS transistor11through a photocoupler16.
