VOLTAGE TRIPLER

■ 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.
