Abstract: PURPOSE: A voltage converting circuit is provided to prevent the transistors of a boosting circuit or a clock generating circuit from being broken by applying a stable voltage downed below an external power supply voltage as a power supply voltage of the voltage converting circuit, not by applying the external power supply voltage as the power supply voltage thereof. CONSTITUTION: The internal power supply voltage converting circuit comprises: an internal power supply voltage generating part(18) for comparing a voltage difference between a reference voltage and a first internal power supply voltage by use of an external power supply voltage(VEXT) as a power supply, wherein the internal power supply voltage generating part maintains the reference voltage; a clock signal generating part(10) for receiving the first internal power supply voltage as a power supply to generate a clock signal(CLK); a boosting part(12) for receiving the external power supply voltage as a power supply to boost the external power supply voltage in response to the clock signal; a differential comparator(14) for receiving the boosted voltage(Vp) as a power supply to compare a voltage difference between the reference voltage and a second internal power supply voltage, wherein the differential comparator(14) increases its output voltage when the second internal power supply voltage is lower than the reference voltage and decreases the output voltage when the second internal power supply voltage is higher than the reference voltage; and a driver for converting the external power supply voltage in response to the output voltage from the differential amplifier to generate the converted voltage as the second internal power supply voltage.
