CMOS Voltage Converters

The Intersil ICL7660 and ICL7660A are monolithic CMOS

power supply circuits which offer unique performance

advantages over previously available devices. The ICL7660

performs supply voltage conversions from positive to

negative for an input range of +1.5V to +10.0V resulting in

complementary output voltages of -1.5V to -10.0V and the

ICL7660A does the same conversions with an input range of

+1.5V to +12.0V resulting in complementary output voltages

of -1.5V to -12.0V. Only 2 noncritical external capacitors are

needed for the charge pump and charge reservoir functions.

The ICL7660 and ICL7660A can also be connected to

function as voltage doublers and will generate output

voltages up to +18.6V with a +10V input.

Contained on the chip are a series DC supply regulator, RC

oscillator, voltage level translator, and 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 5.0V. 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 (+3.5V to +10.0V for

the ICL7660 and +3.5V to +12.0V for the ICL7660A), the LV

pin is left floating to prevent device latchup.
