Product Summary

The SI7661CJ+ is a momolithic charge pump voltage inverter that will convert a positive voltrage in the range of 4.5V to 20V to the correspondng negative voltage of -4.5V to -20V. The SI7661CJ+ provides performance far superior to previous implementations of charge pump voltage inverters by combining low quiescent current with high efficiency. The SI7661CJ+ has an osicllator, control circuitry, and a 4 power MOS switches on-chip, with the only required external components being two low cost capacitors. The applications of the SI7661CJ+ include inexpensive negative supplies, data acquisition systems, up to -20V for Op Amps, and other linerat circuits, supply splitter, VOUT=VS/2 and RS-232 power supplies.

Parametrics

SI7661CJ+ absolute maximum ratings: (1)V+ to GND: -0.3V, +22V; (2)osicllator input to GND: -0.3V, V++0.3; (3)power dissipation: 300mW; (4)operating temperature range: 0 to 70℃; (5)storage temperature: -65 to 160℃; (6)lead temeprature (soldering, 10sec): 300℃.

Features

SI7661CJ+ 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 external capacitors; (5)pin compatible with the ICL7660.
