ICL7662EPA+

ICL7662EPA+ is a CMOS voltage converter. This is a monolithic charge pump voltage inverter that will convert a positive voltage in the range of +4.5V to +20V. It 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 component being two cost capacitors. Suitable for inexpensive negative supplies, data acquisition systems, up to -20V for op-amp and other linear circuits, supply splitter, vout=vs/2, RS-232 power supplies.

• Supply voltage range from 4.5V to 20V and -4.5V to -20V adjustable output
• Cascaded voltage multiplication (vout=-nx V+)
• 99.7% typical open circuit conversion efficiency
• Requires only 2 external capacitors
• Pin compatible with the ICL7660
• Doubler, inverting topology
• 8 pin plastic DIP package
• Temperature range from -40 to 85°C
