A 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure a low-impedance path for the output capacitors and keep the input capacitors close to the IC.
Use a pi-filter configuration with a common-mode choke and a differential-mode inductor. Ensure the output capacitors are placed close to the IC and the output inductor is placed close to the load.
A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value between 10uF to 22uF is recommended. The capacitor should be placed close to the IC and have a low inductance path to the input pin.
Ensure the output capacitor has a low ESR and is placed close to the IC. Also, add a small ceramic capacitor (e.g., 10nF) between the output and ground to improve stability.
The maximum input voltage is 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and minimize power dissipation.
