CHARGE PUMP DC-TO-DC VOLTAGE CONVERTER  
GENERAL DESCRIPTION  
FEATURES  
The TC7660 is a pin-compatible replacement for the  
Industry standard TC7660 charge pump voltage converter.  
It converts a +1.5V to +10V input to a corresponding – 1.5V  
to – 10V output using only two low-cost capacitors, eliminat-  
ing inductors and their associated cost, size and EMI.  
The on-board oscillator operates at a nominal fre-  
quency of 10kHz. Operation below 10kHz (for lower supply  
current applications) is possible by connecting an external  
capacitor from OSC to ground (with pin 1 open).  
The TC7660 is available in both 8-pin DIP and 8-pin  
SOIC packages in commercial and extended temperature  
ranges.  
Converts +5V Logic Supply to ±5V System  
Wide Input Voltage Range .................... 1.5V to 10V  
Efficient Voltage Conversion......................... 99.9%  
Excellent Power Efficiency ............................... 98%  
Low Power Supply...............................80µA @ 5VIN  
Low Cost and Easy to Use  
— Only Two External Capacitors Required  
RS232 Negative Power Supply  
Available in Small Outline (SO) Package  
Improved ESD Protection ....................... Up to 3kV  
No Dx Diode Required for High Voltage Operation
