STMicroelectronics provides a recommended PCB layout in the application note AN4101, which includes guidelines for component placement, routing, and thermal management to minimize EMI and thermal issues.
The inductor value selection depends on the input voltage, output voltage, and output current. A good starting point is to use the inductor selection guide provided in the L5952 datasheet, and then fine-tune the value based on the specific application requirements.
The maximum junction temperature of the L5952 is 150°C, but it's recommended to keep the junction temperature below 125°C for reliable operation and to ensure a long lifespan.
Yes, the L5952 is qualified for automotive and high-reliability applications, and it meets the requirements of the AEC-Q100 standard. However, it's essential to follow the recommended design and manufacturing guidelines to ensure the device meets the specific application requirements.
STMicroelectronics provides a troubleshooting guide in the application note AN4101, which includes a step-by-step approach to identify and fix common issues with the L5952. Additionally, the device's internal protection features, such as overcurrent protection and thermal shutdown, can help identify the root cause of the issue.
