Super Voltage Converter
The ICL7660S Super Voltage Converter is a monolithic
CMOS voltage conversion IC that guarantees significant
performance advantages over other similar devices. It is a
direct replacement for the industry standard ICL7660 offering
an extended operating supply voltage range up to 12V, with
lower supply current. No external diode is needed for the
ICL7660S. In addition, a Frequency Boost pin has been
incorporated to enable the user to achieve lower output
impedance despite using smaller capacitors. All
improvements are highlighted in the Electrical Specifications
section. Critical parameters are guaranteed over the entire
commercial, industrial and military temperature ranges.
The ICL7660S performs supply voltage conversion from
positive to negative for an input range of 1.5V to 12V,
resulting in complementary output voltages of -1.5V to -12V.
Only 2 non-critical external capacitors are needed for the
charge pump and charge reservoir functions. The ICL7660S
can be connected to function as a voltage doubler and will
generate up to 22.8V with a 12V input. It can also be used as
a voltage multiplier or voltage divider.
The chip contains a series DC power supply regulator, RC
oscillator, voltage level translator, and four output power
MOS switches. The oscillator, when unloaded, oscillates at a
nominal frequency of 10kHz for an input supply voltage of
5.0V. This frequency can be lowered by the addition of an
external capacitor to the “OSC” terminal, or the oscillator
may be over-driven by an external clock.
The “LV” terminal may be tied to GND to bypass the internal
series regulator and improve low voltage (LV) operation. At
medium to high voltages (3.5V to 12V), the LV pin is left
floating to prevent device latchup.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. Connecting any terminal to voltages greater than V+ or less than GND may cause destructive latchup. It is recommended that no inputs from
sources operating from external supplies be applied prior to “power up” of ICL7660S.
2. θJA is measured with the component mounted on an evaluation PC board in free air.
