The ICL7662 is a monolithic charge pump voltage inverter taht will convert a positive voltage in the range of +4.5V to +20V to the corresponding negativevoltage of -4.5V to -20V. The ICL7662 provides performance far superior to previous implementations of charge pump voltage inverters by combining low quiescent current with hight efficiency. The ICL7662 has an oscillator, control circuitry, and 4 power MOS switches on-chip, with the only required external components being two low cost capacitors.
