STMicroelectronics recommends a 2-layer PCB with a thermal pad connected to a large copper area on the bottom layer to dissipate heat efficiently.
Use a heat sink with a thermal resistance of 10°C/W or lower, and ensure good airflow around the device. Also, consider using a thermal interface material to improve heat transfer.
The maximum allowed voltage on the input pins is 35V, but it's recommended to keep it below 30V to ensure reliable operation and prevent damage to the device.
Check the input voltage, ensure the enable pin is properly configured, and verify that the device is not in a fault state. Also, check for any short circuits or damage to the device or PCB.
The recommended capacitor value for the output filter is 10uF to 22uF, depending on the specific application and output voltage requirements.
