STMicroelectronics recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure optimal thermal performance.
To ensure reliable operation in high-temperature environments, it is recommended to follow the thermal design guidelines provided by STMicroelectronics, including using a heat sink and ensuring good airflow around the device.
The maximum allowed voltage on the input pins is 40V, but it is recommended to keep the input voltage below 36V to ensure reliable operation.
To troubleshoot issues with the device not turning on, check the input voltage, ensure that the enable pin is properly configured, and verify that the device is properly soldered to the PCB.
The recommended capacitor value for the output filter is 10uF to 22uF, depending on the specific application requirements and noise tolerance.
