Super Voltage Converters
The ICL7660S and ICL7660A Super Voltage Converters are
monolithic CMOS voltage conversion ICs that guarantee
significant performance advantages over other similar
devices. They are direct replacements for the industry
standard ICL7660 offering an extended operating supply
voltage range up to 12V, with lower supply current. 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 on page 3. Critical parameters are
guaranteed over the entire commercial and industrial
temperature ranges.
The ICL7660S and ICL7660A perform supply voltage
conversions from positive to negative for an input range of
1.5V to 12V, resulting in complementary output voltages of
-1.5V to -12V. Only two non-critical external capacitors are
needed, for the charge pump and charge reservoir functions.
The ICL7660S and ICL7660A can be connected to function
as a voltage doubler and will generate up to 22.8V with a
12V input. They can also be used as a voltage multipliers or
voltage dividers.
Each 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.
In some applications, an external Schottky diode from V OUT
to CAP- is needed to guarantee latchup free operation (see
Do’s and Dont’s section on page 8).
