General Description

The TC7660S device is a pin-compatible replacement

for the industry standard 7660 charge pump voltage

converter. It converts a +1.5V to +12V input to a corre-

sponding -1.5V to -12V output using only two low-cost

capacitors, eliminating inductors and their associated

cost, size and electromagnetic interference (EMI).

Added features include an extended supply range to

12V, and a frequency boost pin for higher operating fre-

quency, allowing the use of smaller external capacitors.

The on-board oscillator operates at a nominal fre-

quency of 10 kHz. Frequency is increased to 45 kHz

when pin 1 is connected to V+. Operation below 10 kHz

(for lower supply current applications) is possible by

connecting an external capacitor from OSC to ground

(with pin 1 open).

The TC7660S is available in 8-Pin PDIP and 8-Pin

Small Outline (SOIC) packages in commercial and

extended temperature ranges.
