Characteristics subject to change without notice.

FEATURES

s Replaces MAX660 and LTC®660

s Converts V+ to V- or V+ to 2V+

s Low output resistance, 4

Ω typical

s High power efficiency

s Selectable charge pump frequency

- 10kHz or 80kHz

- Optimize capacitor size

DESCRIPTION

The CAT660 is a charge-pump voltage converter. It will

invert a 1.5V to 5.5V input to a -1.5V to -5.5V output. Only

two external capacitors are needed. With a guaranteed

100mA output current capability, the CAT660 can replace

a switching regulator and its inductor. Lower EMI is

achieved due to the absence of an inductor.

In addition, the CAT660 can double a voltage supplied

from a battery or power supply. Inputs from 2.5V to 5.5V

will yield a doubled, 5V to 11V output voltage.

A Frequency Control pin (BOOST/FC) is provided to

select either a high (80kHz) or low (10kHz) internal

oscillator frequency, thus allowing quiescent current vs.

s Low quiescent current

s Pin-compatible, high-current alternative to

7660/1044

s Industrial temperature range

s Available in 8-pin SOIC and DIP packages

- Lead-free, halogen-free package option

APPLICATIONS

s Negative voltage generator

s Voltage doubler

s Voltage splitter

s Low EMI power source

s GaAs FET biasing

s Lithium battery power supply

s Instrumentation

s LCD contrast bias

s Cellular phones, pagers

TYPICAL APPLICATION

capacitor size trade-offs to be made. The 80kHz

frequency is selected when the FC pin is connected to

V+. The operating frequency can also be adjusted with

an external capacitor at the OSC pin or by driving OSC

with an external clock.

Both 8-pin DIP and SOIC packages are available in the

industrial temperature range.

The CAT660 replaces the MAX660 and the LTC

660.

In addition, the CAT660 is pin compatible with the 7660/

1044, offering an easy upgrade for applications with

100mA loads.
