CN0419 is a circuit that isolates a peripheral device that already implements a USB interface by using the ADuM4160, a USB port isolator based on Analog Devices iCoupler technology. It is bus-powered by pairing it with a small isolated dc-to-dc converter such as the ADuM5020. The application circuit shown is typical of many medical and industrial applications.
The ADuM4160 is a USB port isolator, based on Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics and are easily integrated with low and full speed USB-compatible peripheral devices.
The ADuM5020 is an isoPower®, integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler® technology, this dc-to-dc converter provides regulated, isolated power that is below CISPR22 Class B limits at full load on a 2-layer printed circuit board (PCB) with ferrites.
The EVAL-CN0419-EBZ board connects through a USB Type A Plug and is powered by the bus voltage from the USB port.
