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.
capacitor size trade-offs to be made. The 80kHz
frequency is selected when the FC pin is connected to

TYPICAL APPLICATION
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 TDFN package has a
4x4mm footprint and features a 0.8mm maximum height.
Compared to the 8-pin SOIC the TDFN package footprint
is nearly 50% less. For die availability, contact Catalyst
Semiconductor marketing.
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.
