Overview
- +4.5V to +20V Supply to -4.SV to -20V Output
- Cascaded Voltage Multiplication (VOUT= -n x v•)
- 99.70/o Typical Open Circuit Conversion Efficiency
- Requires Only 2 External Capacitors
- Pin Compatible with the ICL7660
The ICL7662/Si7661 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 ICL 7662/Si7661 provides performance far superior to previous implementations of charge pump voltage inverters by combining low quiescent current with high efficiency. The ICL7662/Si7661 has an oscillator, control circuitry, and 4 power MOS switches on-chip, with the only required external components being two low cost capacitors.
APPLICATIONS
- Inexpensive Negative Supplies
- Data Acquisition Systems
- Up to -20V for Op Amps, and Other Linear Circuits
- Supply Splitter, VOUT = Vs/2
- RS-232 Power Supplies
