STMicroelectronics provides a recommended PCB layout in the application note AN4101, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
The selection of the inductor depends on the specific application requirements, such as the input voltage, output voltage, and output current. STMicroelectronics provides a list of recommended inductors in the datasheet, and also offers an inductor selection tool on their website to help engineers choose the right inductor for their design.
The maximum junction temperature (Tj) for the L6585D is 150°C, as specified in the datasheet. However, it's recommended to keep the junction temperature below 125°C to ensure reliable operation and long-term reliability.
While the L6585D can operate up to 150°C, it's not recommended to use it in high-temperature environments above 125°C without proper thermal management and derating. STMicroelectronics provides thermal derating curves in the datasheet to help engineers design for high-temperature applications.
STMicroelectronics provides a troubleshooting guide in the application note AN4101, which includes common issues and their solutions, such as checking the PCB layout, component values, and input/output voltage levels. Additionally, engineers can use simulation tools and oscilloscopes to debug and analyze the circuit behavior.
