Product Summary

The ICL7662EBA+T is a monolithic charge pump voltage inverter that will convert a positive voltage in the range of +4.5V to +20V to the corresponding negative voltage of -4.5V to -20V. The ICL7662EBA+T provides performance far supperior to previous implementations of charge pump voltage inverters by combining low quiescent current with high efficiency. The ICL7662EBA+T has an oscillator, control circuitry and 4 power MOS switches on-chip, with the only required external components being two low cost capacitors.The applications of the ICL7662EBA+T include inexpensive negative supplies, data acquisition systems, up to -20V for Op Amps, and other linear circuits, supply splitter and RS-232 power supplies.

Parametrics

ICL7662EBA+T absolute maximum ratings: (1)V+ to GND: -0.3V, +22V; (2)oscillator input to GND: -0.3V, V++0.3V when V-<12V; V+-12.3V, V++0.3V when V+>12V; (3)power dissipaton: 300mW; (4)operating temperature ranges: 0 to 70℃; (5)storage temperature: -65 to 160℃; (6)lead temperature (soldering, 10sec): 300℃.

Features

ICL7662EBA+T features: (1)+4.5V to +20V supply to -4.5V to -20V output; (2)cascaded voltage multiplication; (3)99.7% typical open circuit conversion efficiency; (4)requires only 2 wxternal capacitors; (5)pin compatible with the ICL7660.
