STMicroelectronics provides a recommended PCB layout in the application note AN4571, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
The inductor value depends on the input voltage, output voltage, and switching frequency. STMicroelectronics provides an inductor selection guide in the datasheet, and you can also use online inductor selection tools or consult with an applications engineer for specific guidance.
While the datasheet specifies an operating temperature range of -40°C to 150°C, the maximum ambient temperature for reliable operation depends on the specific application and thermal design. As a general guideline, it's recommended to keep the ambient temperature below 125°C to ensure reliable operation and minimize thermal stress.
STMicroelectronics provides a troubleshooting guide in the application note AN4571, which covers common issues and their solutions. Additionally, you can consult with an applications engineer or use online resources, such as forums and knowledge bases, to find solutions to specific problems.
The recommended components for the input filter and output filter are specified in the datasheet and application notes. However, the specific component values may vary depending on the application requirements and PCB layout. It's recommended to consult with an applications engineer or use online resources to find the optimal component values for your specific design.
