Maxim Integrated (ICL7662CPA+) DC/DC Charge Pump Voltage Regulator

DC/DC Charge Pump Voltage Regulator, 4.5V to 20V in, -20V to -4.5V out, DIP-8

Product Overview
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
