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.
