VOLTAGE TRIPLER
NJU7670
■ 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.
