CMOS Voltage Converter  
Features  
The Intersil ICL7662 is a monolithic high-voltage CMOS  
power supply circuit which offers unique performance ad-

L76 vantages over previously available devices. The ICL7662  
• Pin Compatible With ICL7660  
performs supply voltage conversion from positive to negative

• Simple Conversion of +15V Supply to -15V Supply  
for an input range of +4.5V to +20.0V, resulting in  
complementary output voltages of -4.5V to -20V. Only 2  
noncritical external capacitors are needed for the charge  
pump and charge reservoir functions. The ICL7662 can also  
function as a voltage doubler, and will generate output  
voltages up to +38.6V with a +20V input.

voltage in the device and ensures that the output N-Channel  
switch source-substrate junctions are not forward biased.  
This assures latchup free operation.  
Applications  
• On Board Negative Supply for Dynamic RAMs  
• Localized µProcessor (8080 Type) Negative Supplies  
• Inexpensive Negative Supplies  
• Data Acquisition Systems  
The oscillator, when unloaded, oscillates at a nominal  
frequency of 10kHz for an input supply voltage of 15.0V. This  
frequency can be lowered by the addition of an external  
capacitor to the “OSC” terminal, or the oscillator may be  
ter-  
rpo-  
ion,  
overdriven by an external clock.

• Up to -20V for Op Amps  
The “LV” terminal may be tied to GROUND to bypass the

internal series regulator and improve low voltage (LV)

operation. At medium to high voltages (+10V to +20V), the  
e
LV pin is left floating to prevent device latchup.
