Mpression +/-12V Output Isolated DC/DC Board with LT8302

Mpression +/-12V Output Isolated DC/DC Board with LT8302 is designed to develop industrial control applications. Industrial equipment like Programmable Logic Controllers (PLC) that are connected to field bus networks requires a high precision positive and negative power supply to accommodate analog signal processing circuitry for sensors. The power needs to be isolated to avoid unexpected damages at sensor nodes to spread to the whole system. This reference board is designed using Analog Devices isolated voltage controller (LT8302) and Wurth Elektronik general-purpose transformer (750313443). The availability of transformers is often a problem for using an isolated voltage controller, but this design is more easily adopted as it uses a general-purpose transformer.
