CMOS Voltage Converter
The Intersil ICL7662 is a monolithic high-voltage CMOS
power supply circuit which offers unique performance ad-
vantages over previously available devices. The ICL7662
performs supply voltage conversion from positive to negative
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.
Contained on chip are a series DC power supply regulator,
RC oscillator, voltage level translator, four output power MOS
switches. A unique logic element senses the most negative
voltage in the device and ensures that the output N-Channel
switch source-substrate junctions are not forward biased.
This assures latchup free operation.
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
overdriven by an external clock.
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
LV pin is left floating to prevent device latchup.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
2. Connecting any terminal to voltages greater than V+ or less than GND may cause destructive latchup. It is recommended that no inputs from
sources operating from external supplies be applied prior to “power up” of ICL7660S.
3. θJA is measured with the component mounted on an evaluation PC board in free air.
Electrical Specifications V+ = 15V, TA = 25oC, COSC = 0, Unless Otherwise Specified. Refer to Figure 14.

NOTE:
4. Pin 1 is a Test pin and is not connected in normal use. When the TEST pin is connected to V+, an internal transmission gate disconnects any
external parasitic capacitance from the oscillator which would otherwise reduce the oscillator frequency from its nominal value.
