DESCRIPTION

The CAT661 is a charge-pump voltage converter. It can

invert a positive input voltage to a negative output. Only

two external capacitors are needed. With a guaranteed

100mAoutputcurrentcapability,theCAT661canreplace

a switching regulator and its inductor. Lower EMI is

achieved due to the absence of an inductor.

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 SO packages are available. The

TDFN package 4x4mm footprint features a 0.8mm

maximum height. For die availability, contact Catalyst

Semiconductor marketing.

In addition, the CAT661 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.

The CAT661 can replace the MAX660 and the LTC660

in applications where higher oscillator frequency and

smaller capacitors are needed. In addition, the CAT661

is pin compatible with the 7660/1044, offering an easy

upgrade for applications with 100mA loads.

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

select either a high (typically 135kHz) or low (25kHz)

internal oscillator frequency, thus allowing quiescent

current vs. capacitor size trade-offs to be made. The

135kHz frequency is selected when the FC pin is
