- Faster propagation delay than UCC21520 (vs UCC21520DW)
Design Notes
For optimal performance, place the ADUM4222ARWZ-RL7 close to the power switches to minimize gate loop inductance. Use separate ground planes for primary and secondary sides, and maintain proper creepage distances for 5000 Vrms isolation. Refer to the datasheet layout guidelines for recommended PCB stack-up.
Ensure adequate decoupling on VDD1 and VDD2 with low-ESR ceramic capacitors (e.g., 0.1 µF and 10 µF) placed close to the pins. The 4 A peak output current can cause supply droop; a bulk capacitor on VDD2 is recommended to maintain gate drive voltage during switching.
The ADUM4222ARWZ-RL7 dissipates power proportional to switching frequency and gate charge. For high-frequency operation, calculate power dissipation and ensure the SOIC package has adequate copper area for heat sinking. The device's thermal resistance is not specified in the provided data; refer to the datasheet for thermal metrics.
