The following is the circuit diagram of the Polarity Conversion Power Supply ICL7660. This power supply utilizes the ICL7660, a specialized integrated circuit for polarity conversion, along with two external capacitors to achieve DC/DC voltage inversion. The design employs a charge pump technique, which ensures high efficiency—up to 95%—and low power consumption. The quiescent current is only 0.5mA, and it can provide an output current ranging from 10 to 20mA, making it ideal for low-power applications.
The ICL7660 is known for its reliability and simplicity in implementation. It allows for easy conversion between positive and negative voltages without the need for inductors or transformers, which reduces the overall size and complexity of the circuit. This makes it particularly useful in portable devices, battery-powered systems, and other applications where space and efficiency are critical.
