ABSTRACT:
A voltage conversion circuit has a pulse generator that generates a pulse signal having a fixed pulse width and a variable pulse period. The output voltage of this voltage conversion circuit is determined according to the ratio of the pulse width to the pulse period of the pulse signal generated by the pulse generator. This circuit configuration makes it possible to produce as the output voltage lower voltages than ever.
