STMicroelectronics provides a recommended PCB layout in the application note AN2552, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and thermal dissipation.
The input capacitor values depend on the input voltage, frequency, and desired ripple rejection. A general rule of thumb is to use a 10uF to 22uF capacitor with a voltage rating of at least 2x the input voltage. However, it's recommended to consult the application note AN2552 for more detailed guidance.
The maximum power dissipation of the TDA7391PD is dependent on the ambient temperature and the thermal resistance of the package. According to the datasheet, the maximum power dissipation is 2.5W at 25°C ambient temperature. However, it's recommended to consult the thermal management section of the datasheet for more detailed information.
The TDA7391PD is rated for operation up to 150°C junction temperature. However, the device's performance and reliability may degrade at high temperatures. It's recommended to consult the datasheet and application notes for guidance on thermal management and derating the device for high-temperature operation.
STMicroelectronics provides a troubleshooting guide in the application note AN2552, which covers common issues such as oscillations, noise, and thermal shutdown. Additionally, it's recommended to consult the datasheet and application notes for guidance on debugging and troubleshooting techniques.
