General Description

The TC7660 is a pin-compatible replacement for the

industry standard 7660 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, eliminating inductors and their

associated cost, size and electromagnetic interference

(EMI).

Applications

• RS-232 Negative Power Supply

• Simple Conversion of +5V to ±5V Supplies

• Voltage Multiplication V

• Negative Supplies for Data Acquisition Systems

and Instrumentation

= ± n V

OUT

The on-board oscillator operates at

a nominal

frequency of 10 kHz. Operation below 10 kHz (for

lower supply current applications) is possible by

connecting an external capacitor from OSC to ground.

The TC7660 is available in 8-Pin PDIP, 8-Pin Small

Outline (SOIC) and 8-Pin CERDIP packages in

commercial and extended temperature ranges.
