Key Differentiators
- Higher isolation voltage than ADUM3223ARWZ-RL7 (vs ADUM3223ARWZ-RL7)
- Automotive-grade variant available (vs ADUM4223ARWZ)
- Faster propagation delay than UCC21520DW (vs UCC21520DW)
Design Notes
Maintain proper creepage and clearance distances for 5000 Vrms isolation. The wide-body SOIC-16 package provides 8 mm creepage, but ensure PCB layout follows IPC-2221 standards. Keep high-voltage traces away from low-voltage control circuitry, and use a ground plane on the input side to reduce noise coupling.
Decouple VDD1 and VDD2 with 0.1 uF and 10 uF capacitors placed close to the pins. The input supply (VDD1) should be stable between 2.5 V and 6.5 V, while the output supply (VDD2) can range from 4.5 V to 35 V. Use low-ESR ceramic capacitors to handle high di/dt during switching.
The ADUM4223ARWZ-RL7 dissipates power proportional to switching frequency and gate charge. At 1 MHz with 100 nC gate charge, power dissipation is approximately 0.4 W. Ensure adequate copper area on the PCB for heat dissipation, and consider thermal vias if operating at high ambient temperatures.
