Abstract
An internal power supply auxiliary circuit supplies a current to a power generator circuit. A pulse signal generator receives an input signal and outputs a first control signal. A driver circuit connected to the pulse signal generator receives the first control signal, an external supply voltage and a source voltage, and generates a drive pulse signal. A current supply driver circuit receives the drive pulse signal and the external supply voltage and outputs the supply current to the power generator circuit. A gate voltage regulator circuit connected to the driver circuit receives a reference voltage and produces the source voltage. The gate voltage regulator causes the source voltage to substantially match the reference voltage so that the current supplied to the power generator circuit does not exceed a predetermined value.
