This article describes the Miniature Voltage Isolation Provides Positive and Negative Supply (DCP010512DBP). The principle is very simple, very practical. The circuit components can help you understand better grasp this principle. For example, in this circuit, you can go to find and buy these components:DCP010512DBP.

The development of miniature low-power (<2-W) DC/DC converters is growing rapidly because of the hot growth in distributed-power architecture. This application minimize the converter’s impact onboard space. This device is very useful for safety-critical applications such as medical equipment, and telecommunications, and industrial applications because it provides point-of-use isolated power conversion for analog circuitry. In addition, this device can be used to reduce noise and galvanically isolate output power. The following figures show miniature isolated DC/DC converter in standard IC package, IC lead-frame and the schematic diagram of the device :

Usually, to create positive and negative output voltages to op amp we need some board space. It can be reduced by using miniature DC/DC converters in standard IC packaging. The operating input voltage of this circuit is 4.5 to 5.5 V. To create unregulated output voltages with a magnitude higher than its 5-V input, this circuit use the dual-output converter. It performs a buck boost function with a -12V output and boost function that creates a 12V output.
