General Description

The TC7660 device is a pin-compatible replacement

for the industry standard 7660 charge pump voltage

converter. It converts a +1.5V to +10V input to a corre-

sponding -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_OUT= ± n V⁺

• Negative Supplies for Data Acquisition Systems

and Instrumentation

The on-board oscillator operates at a nominal fre-

quency 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.
