- 2.5 kVrms isolation rating (vs ADUM1412ARWZ)
Design Notes
For optimal isolation performance, maintain a clean separation between the input and output grounds. Do not route copper traces under the isolation barrier. Use a solid ground plane on each side, and place decoupling capacitors (0.1 Β΅F and 10 Β΅F) close to the VDD1 and VISO pins. The recommended PCB layout is shown in the ADuM5401/5402/5403/5404 datasheet.
The integrated isoPower converter can deliver up to 500 mW. Ensure that the total load on the isolated side does not exceed this limit. If more power is needed, consider using an external isolated DC-DC converter. The input supply should be capable of providing sufficient current; for 5 V input, the typical input current is [DATA_NEEDED] mA at full load. Use low-ESR capacitors on the input and output to minimize ripple.
The ADUM5414ARWZ dissipates power internally due to the integrated DC-DC converter. At maximum load, the power dissipation can be significant. Ensure adequate thermal management by providing copper pour on the PCB and ensuring proper airflow. The thermal resistance from junction to ambient (ΞΈJA) is [DATA_NEEDED] Β°C/W. For high ambient temperatures, derate the output power accordingly.
