What are the key features of ICL7660CUA?
- Inductor-free voltage inversion using only 2 external capacitors generates a negative rail from a positive supply, simplifying bipolar-supply PCB designs
- Wide input range from 1.5 V to 10 V covers single-cell battery, USB 5 V, and regulated 3.3 V rails without design changes
- Up to 20 mA output current supports dual-supply op-amp circuits, LCD bias generators, and low-power analog front ends
- Switched-capacitor architecture achieves high conversion efficiency at light loads, extending battery life in portable instrumentation
What is ICL7660CUA used for?
ICL7660CUA is widely used to generate a negative supply rail for dual-supply op-amp circuits in portable instruments and handheld test equipment that operate from a single positive battery. It also provides the negative bias voltage needed for LCD contrast adjustment in embedded systems and industrial panel displays without a bulky inductor-based inverter. In addition, the device serves as a voltage doubler in low-power RF or sensor circuits where a higher rail derived from a 3.3 V or 5 V source is required.

Frequently Asked Questions
Which supply rails can ICL7660CUA invert or double without using an inductor?
ICL7660CUA is intended for switched-capacitor conversion from a 1.5 V to 10 V input range, supporting voltage inversion or doubling without an inductor in compact low-current rails.
How should procurement teams judge load-current fit for ICL7660CUA?
Use ICL7660CUA where the converted rail needs up to 20 mA output current, such as bias supplies, interface circuits, or analog support rails rather than high-power loads.
For a compact PCB, what external parts does ICL7660CUA usually need?
The device typically works with 2 external capacitors, so designers can build a small switched-capacitor converter around the small-outline package without magnetic components.
