Rev 7.01
Feb 10, 2020 Super Voltage Converters
The ICL7660S and ICL7660A Super Voltage Converters are
monolithic CMOS voltage conversion ICs that ensure
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
ensured 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 …
