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

• Simple Conversion of +5V Logic Supply to ±5V Supplies

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 Voltage Multiplication V

= (-)nV

OUT

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

Passive Components

• Improved Direct Replacement for Industry Standard

ICL7660 and Other Second Source Devices

• Pb-Free Plus Anneal Available (RoHS Compliant)

Applications

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.

• Simple Conversion of +5V to ±5V Supplies

• Voltage Multiplication V

= ±nV

OUT

• Negative Supplies for Data Acquisition Systems and

Instrumentation

• RS232 Power Supplies

• Supply Splitter, V

OUT

= ±V /2

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.
