A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the package can help to dissipate heat efficiently. It's also recommended to keep the thermal path short and direct to the heat sink or chassis.
To ensure reliable start-up and shutdown, add a soft-start circuit to limit the inrush current and prevent voltage drops. Also, use a capacitor with a low equivalent series resistance (ESR) to filter the output voltage.
Although the datasheet specifies a maximum input voltage of 35V, it's recommended to limit the input voltage to 30V to ensure reliable operation and prevent damage to the internal circuitry.
Use an external current sense resistor and a fuse to detect overcurrent conditions. Also, implement thermal monitoring and shutdown circuitry to prevent overheating. Additionally, ensure good airflow and a heat sink to dissipate heat efficiently.
While the regulator is rated for operation up to 125°C, it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation. Consult the datasheet and application notes for more information.
