Power Supply Splitter 9V to ± 5V

Power supply splitter

This power supply splitter circuit can divide the voltage of ± 5V only from a 9V battery. This circuit consists of three ICs. The first is IC ICL7660, these are monolithic, CMOS switched-capacitor voltage converters that invert, double, divide, or multiply a positive input voltage. Next is ICL7663 IC a positive voltage regulator. And the last ICL7664 for negative voltage regulator.

The oscillation frequency of the ICL7660 will be reduced with the external oscillator capacitor, so that it inverts the battery voltage more efficiently.

Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.
