ABSTRACT:
A voltage tripler which uses a charge pump with a single charge transfer capacitor to produce the required voltage is disclosed. The voltage tripler in conjunction with an inverter is useful for producing voltages with negative polarities. The voltage tripler when used in conjunction with a variable frequency oscillator circuit is useful in optimizing the power consumption by the charge pump of the voltage tripler when the tripler is not operating under load conditions. The tripler is useful in supplying power to a combination RS232 and RS422 or RS232 and RS485 interface, as well as other monolithic interface products.
