A 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure that the thermal pad is connected to a large copper area to dissipate heat efficiently.
Use a soft-start circuit to limit the inrush current during startup. For shutdown, ensure a gradual decrease in input voltage to prevent voltage spikes.
Use a common-mode choke, X-capacitors, and Y-capacitors to filter EMI. Ensure that the layout is optimized to minimize loop areas and reduce radiation.
Use a low-dropout regulator for the bias supply, and consider using a low-power mode or shutdown feature to reduce standby power consumption.
Ensure good thermal conduction between the device and the heat sink, and consider using thermal interface materials to reduce thermal resistance.
