ICL7660S  
Data Sheet

File Number 3179.2  
Super Voltage Converter  
Features  
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  
• 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 Voltage  
Range  
• Boost Pin (Pin 1) for Higher Switching Frequency  
• Guaranteed Minimum Power Efficiency of 96%  
improvements are highlighted in the Electrical Specifications  
section. Critical parameters are guaranteed over the entire  
commercial, industrial and military temperature ranges.  
• Improved Minimum Open Circuit Voltage Conversion  
Efficiency of 99%  
• Improved SCR Latchup Protection  
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.  
• Simple Conversion of +5V Logic Supply to ±5V Supplies  
• Simple Voltage Multiplication V  
OUT  
= (-)nV  
IN  
• Easy to Use - Requires Only 2 External Non-Critical  
Passive Components  
• Improved Direct Replacement for Industry Standard  
ICL7660 and Other Second Source Devices  
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.  
Applications  
• Simple Conversion of +5V to ±5V Supplies  
• Voltage Multiplication V  
OUT  
= ±nV  
IN  
• Negative Supplies for Data Acquisition Systems and  
Instrumentation  
• RS232 Power Supplies  
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.
