Isolated power is found in many different module blocks of an industrial system. For example, on this slide the blocks in yellow highlight where isolated power may be required. Analog Devices' transformer drivers provide a simple building block for isolated power supply designs to enable customers with faster time to market. Application examples include: isolated power for the fieldbus (i.e., RS485, CAN), for diagnostic ports such as USB or RS232, for I/O cards (this includes both digital and analog), and isolated power for sensor modules.
