ICL7662

CMOS Voltage Converter

April 1994

Features

Description

• No External Diode Needed Over Entire Temperature The Harris ICL7662 is a monolithic high-voltage CMOS

Range

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 comple-

mentary 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.

• Pin Compatible With ICL7660

• Simple Conversion of +15V Supply to -15V Supply

• Simple Voltage Multiplication (V_OUT= (-)nV_IN)

• 99.9% Typical Open Circuit Voltage Conversion

Efﬁciency

• 96% Typical Power Efﬁciency

• Wide Operating Voltage Range 4.5V to 20.0V

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.

• Easy to Use - Requires Only 2 External Non-Critical

Passive Components

Applications

• On Board Negative Supply for Dynamic RAMs

• Localized µProcessor (8080 Type) Negative Supplies

• Inexpensive Negative Supplies

The oscillator, when unloaded, oscillates at a nominal fre-

quency 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.

• Data Acquisition Systems

• 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) opera-

tion. At medium to high voltages (+10V to +20V), the LV pin

is left ﬂoating to prevent device latchup.
