Design Notes
Place the external transformer and rectifier diodes for the integrated DC-DC converter close to the ADM2587EBRWZ to minimize parasitic inductance. Use a ferrite bead and decoupling capacitors on both VCC and VISO pins. Ensure a solid ground plane under the device to reduce noise and improve CMTI performance.
Keep the isolation barrier clear of copper traces and components to maintain the specified isolation voltage. Maintain at least 8mm creepage distance between the logic side and bus side on the PCB. Use proper slotting if necessary to increase creepage distance.
The ADM2587EBRWZ dissipates power due to the integrated DC-DC converter. At maximum load, the device may dissipate up to 1W. Ensure adequate copper area on the PCB for heat dissipation, and consider thermal vias under the exposed pad if available. The operating temperature range is -40°C to +85°C.
