7662CPA – Charge Pump DC To DC Converter – DIP-8 Package
The Intersil ICL7662 is a monolithic high-voltage CMOS power supply circuit that offers unique performance ad vantages over previously available devices. The ICL7662 converts supply voltage from positive to negative for an input range of +4.5V to +20.0V, resulting in complementary output voltages of -4.5V to -20V. Only 2 noncritical external capacitors are needed for the charge pump and charge reservoir functions. The ICL7662 can also function as a voltage doubler, generating output voltages up to +38.6V with a +20V input. A series DC power supply regulator, RC oscillator, voltage level translator, and four output power MOS switches are on the chip. A unique logic element senses the most negative voltage in the device and ensures that the output N Channel switch source-substrate junctions are not forward-biased. This assures latchup-free operation. The oscillator, when unloaded, oscillates at a nominal frequency of 10kHz for an input supply voltage of 15.0V. This frequency can be lowered by the addition of an external capacitor to the “OSC” terminal, or the oscillator may be overdriven by an external clock.
