Overview
ICL7660S Data Sheet April 1999 File Number 3179.
2 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.
Features • Guaranteed Lower Max Supply Current for All Temperature Ranges • Wide Operating Voltage Range 1.
5V to 12V • 100% Tested at 3V • No External Diode Over Full Temperature and Vol...
