DATASHEET ICL7660S, ICL7660A FN3179 Rev 7.00 Super Voltage Converters January 23, 2013 The ICL7660S and ICL7660A Super Voltage Converters are Features monolithic CMOS voltage conversion ICs that guarantee Guaranteed Lower Max Supply Current for All significant performance advantages over other similar Temperature Ranges devices. They are direct replacements for the industry Wide Operating Voltage Range: 1.5V to 12V standard ICL7660 offering an extended operating supply voltage range up to 12V, with lower supply current. A 100% Tested at 3V Frequency Boost pin has been incorporated to enable the Boost Pin (Pin 1) for Higher Switching Frequency user to achieve lower output impedance despite using smaller capacitors. All improvements are highlighted in the Electrical Guaranteed Minimum Power Efficiency of 96% Specifications section on page 3. Critical parameters are Improved Minimum Open Circuit Voltage Conversion guaranteed over the entire commercial and industrial Efficiency of 99% temperature ranges. Improved SCR Latchup Protection The ICL7660S and ICL7660A perform supply voltage Simple Conversion of +5V Logic Supply to 5V Supplies conversions from positive to negative for an input range of 1.5V to 12V, resulting in complementary output voltages of Simple Voltage Multiplication V = (-)nV OUT IN -1.5V to -12V. Only two non-critical external capacitors are Easy to Use Requires Only Two External Non-Critical needed, for the charge pump and charge reservoir functions. Passive Components The ICL7660S and ICL7660A can be connected to function as a voltage doubler and will generate up to 22.8V with a Improved Direct Replacement for Industry Standard ICL7660 and Other Second Source Devices 12V input. They can also be used as a voltage multipliers or voltage dividers. Pb-Free Available (RoHS Compliant) Each chip contains a series DC power supply regulator, RC Applications oscillator, voltage level translator, and four output power MOS switches. The oscillator, when unloaded, oscillates at a Simple Conversion of +5V to 5V Supplies nominal frequency of 10kHz for an input supply voltage of Voltage Multiplication V = nV OUT IN 5.0V. This frequency can be lowered by the addition of an Negative Supplies for Data Acquisition Systems and external capacitor to the OSC terminal, or the oscillator Instrumentation may be over-driven by an external clock. RS232 Power Supplies The LV terminal may be tied to GND to bypass the internal series regulator and improve low voltage (LV) operation. At Supply Splitter, V = V OUT S medium to high voltages (3.5V to 12V), the LV pin is left floating to prevent device latchup. In some applications, an external Schottky diode from V OUT to CAP- is needed to guarantee latchup free operation (see Dos and Donts section on page 8).
