■ GENERAL DESCRIPTION
The NJU7670 is a voltage tripler incorporated CR oscillator, voltage converter, reference voltage circuit and voltage regulator.
It can generates triple or double negative voltage of an operating voltage ranging from -2.6V to -6V.
The application circuit of tripler requires three capacitors, and doubler requires only two capacitors.
Furthermore, any kind of output voltage is available by the internal voltage regulator.
