This Evaluation Board is a complete isolated RS-485 / RS-422 node using the IL4622E isolated transceiver with integrated isolated DC-DC convertor.
The 4 by 3 inch (100 x 75 mm) board provides screw terminal and test point connections, and uses a 2s2p board with thermal vias for optimal thermal performance.
The IL4622E is a high-speed, fully-isolated, full duplex differential bus transceiver with an integrated
3.3-to-3.3 volt DC-DC convertor to provide a fully-isolated 3.3 volt bus supply using the controller supply. This level of integration dramatically reduces chip count and board area.
