TDK recommends a symmetrical PCB layout with a solid ground plane, and keeping the input and output traces as short as possible. A 4-layer PCB with a dedicated power plane and a solid ground plane is also recommended.
Ensure good thermal design and heat dissipation by providing adequate airflow, using a heat sink if necessary, and keeping the device away from heat sources. Monitor the device's temperature using the thermal pad or an external temperature sensor.
TDK recommends keeping the input voltage deviation within ±10% of the nominal input voltage to ensure stable operation and prevent damage to the device.
Use proper shielding, filtering, and grounding techniques to minimize EMI and RFI. TDK recommends using a metal shield around the device, and adding EMI filters or ferrite beads to the input and output lines.
TDK recommends a soldering temperature of 260°C (500°F) and a soldering time of 3-5 seconds. Ensure that the soldering process is done in a controlled environment to prevent damage to the device.
