ABSTRACT:
A voltage down converter for converting an external power voltage into an internal power voltage and providing the internal power voltage to an internal circuitry, comprising: a reference voltage generation means for receiving the external power voltage and generating a constant reference voltage where variation of the external power voltage and change of circumstance temperature are compensated; a reference voltage converting means for converting the reference voltage from the reference voltage generation means into a reference voltage for stress mode or a reference voltage for normal mode; and a driving means for receiving the reference voltage from the reference voltage converting means to generate the internal power voltage required to operation of the internal circuitry.
