ICL7662CPA+

The ICL7662CPA+ is a CMOS voltage converter in 8 pin DIP package. This converter is monolithic charge pump voltage inverter that will convert a positive voltage in range of +4.5V to +20V to corresponding negative voltage of -4.5V to -20V. The device provides performance far superior to previous implementations of charge pump voltage inverters by combining low quiescent current with high efficiency. It has an oscillator, control circuitry and 4 power MOS switches on-chip with only required external components being two low cost capacitors. It is used in inexpensive negative supplies, data acquisition systems, supply splitter, Vout = Vs/2, RS-232 power supplies and up to -20V for op amps and other linear circuits.

• Supply voltage of +4.5V to +20V to -4.5V to -20V output
• Operating temperature range from 0°C to +70°C
• Cascade voltage multiplication (Vout = n x V⁺)
• 99.9% typical open circuit conversion efficiency
• Requires only 2 external capacitors
• Pin compatible with ICL7660
• Supply current of 20μA at TA = +25°C (V+ = 5V)
• Output source resistance of 125ohm at TA = +25°C (V+ = 5V)
• Oscillator frequency is 10KHz
