Miniature Voltage Isolation Provides Positive and Negative Supply

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 […]
