ICL7662EBA+T Function Overview

The ICL7662EBA+T is a CMOS voltage converter in 8 pin NSOIC package. This is a monolithic charge pump voltage inverter which converts positive voltage in the range of 4.5V to 20V to the corresponding negative voltage -4.5V to -20V. It provides performance far superior to previous implementation of charge pump voltage inverters by combining low quiescent current with high efficiency and it has an oscillator, control circuitry and 4 power MOS switches on-chip with only two external low cost capacitor required. This device is used in data acquisition systems and RS232 power supplies.
Cascaded voltage multiplication (Vout = -n x Vᶧ)
Operating temperature range from -40°C to 85°C
Supply current is 0.25mA at TA = 25°C and LV = open
Typical open circuit conversion efficiency of 99.7%
Pin compatible with ICL7660
Oscillator frequency of 10KHz
Oscillator sink or source current is 4µA at V+ = 15V
