  • Patent number: 5247239
    Abstract: A voltage converter for stably converting, even a low input voltage, to a predetermined output level is provided. The output of cell 20 is increased by first and second step-up circuits 21 and 22, and then smoothed by smoothing circuit 31. The output is converted by the first step-up circuit from the start of voltage conversion until a predetermined output voltage, and then converted by the second step-up converter thereafter. The output voltage of smoothing circuit 31 is compared against a first reference voltage by first comparator circuit 35, the output of which activates the integral circuit in second comparator circuit 37. The charge voltage of the integral circuit is compared to a sawtooth wave STW generated by oscillator circuit 43 to derive a signal for forcefully shutting down MOS transistor 29 in the second step-up circuit.
