Product Overview

The SI7661ESA+ is a CMOS voltage converter in 8 pin NSOIC package. This monolithic charge pump voltage inverter will convert a positive voltage in the range of +4.5V to +20V to -4.5V to -20V. The IC provides performance far superior to previous implementations of charge pump voltage inverter by combining low quiescent current with high efficiency. It has an oscillator, control circuitry and 4 power MOS switches on-chip with the only required external components being two low cost capacitors. It is used in inexpensive negative supplies, data acquisition systems, supply splitter, Vout=Vs/2 and RS232 power supplies.
  • Supply voltage range is 4.5V to 20V
  • Operating temperature range from -40°C to 85°C
  • Maximum supply current of 150µA at TA = 25°C, V+=5V
  • Cascaded voltage multiplication (Vout = -n x V⁺)
  • Typical open circuit conversion efficiency is 99.7%
  • Pin compatible with the ICL7660
