ICL7662CBA+

The ICL7662CBA+ is a monolithic charge Pump Voltage Inverter for inexpensive negative supplies. The pump voltage inverter that will convert a positive voltage in the range of +4.5 to +20V to the corresponding negative voltage of -4.5 to -20V. The ICL7662 provides performance far superior to previous implementations of charge pump voltage inverters by combining low quiescent current with high efficiency. The ICL7662 has an oscillator, control circuitry and 4 power MOS switches on-chip, with the only required external components being two capacitors.

• Cascaded voltage multiplication
• 99.70% Typical open circuit conversion efficiency
