+/-18V Isolated DC-DC Converter Dual Supply Output from USB 5V Power Input
This is a mini DC-DC converter with dual output from single 5V DC supply or USB power source (e.g., +/-18V from 5V/USB). The mini board will fit into small space and perform with high efficiency. Basically, the circuit transfers power from 5V/USB to the output side +/-18V with high isolation, without a direct connection between 5V/USB power and output. The power isolation prevents ground loops and provides high noise immunity between input and output. The project is based on SN6501 chip, which is oscillator/power-driver, is specifically designed for small factor devices. The device drives a low profile, center-tapped transformer primary from 5V/USB power and secondary side provides unregulated dual output which can be further regulated as per requirement (e.g., +/-5V, +/-12V). Project is a very easy and simple tool to test and run industrial, scientific project, PLC and I/O modules which require dual output from single input. D2 power LED, CN1 USB A type connector for USB power input, CN3 No isolated 3.3V and 5V DC output, CN2 unregulated dual 18V Output.
