主要差異化特點
- Integrated isolated DC-DC converter (對比ADUM3211WBRZ-RL7)
- Higher data rate and CMTI (對比ADUM5212ARSZ-RL7)
- Wide SOIC-W package for better creepage (對比ADUM5412BRSZ-RL7)
設計說明
The integrated DC-DC converter requires proper input and output decoupling. Place a 10 µF ceramic capacitor on VDD1 and a 10 µF capacitor on VISO to ensure stable operation. The output voltage is set by an external resistor divider; use 1% tolerance resistors for accurate regulation. The converter can deliver up to [DATA_NEEDED: output current] mA, so ensure the load does not exceed this limit.
For optimal isolation performance, maintain a minimum creepage distance of 8 mm between primary and secondary sides on the PCB. Use a solid ground plane under the device and avoid routing high-speed signals near the isolation barrier. The SOIC-W package has a wide body, which helps achieve the required creepage. Follow the layout guidelines in the datasheet for best EMI performance.
Do not exceed the absolute maximum ratings for VDD1 and VISO. Ensure the isolated output voltage is set within the specified range (3.15V to 5.25V). When synchronizing multiple devices, use the SYNC pin to reduce EMI; refer to the datasheet for proper connection. Also, note that the 'A' grade has specific performance characteristics; verify if you need the 'B' grade for higher data rates.
