Texas Instruments provides a recommended PCB layout in the application note SLVAE03, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
The thermal shutdown feature is enabled by default and will shut down the device if the junction temperature exceeds 150°C. To handle this, ensure proper thermal design and heat sinking, and consider using thermal monitoring and shutdown detection circuits in your design.
The recommended input capacitance is 10nF to 100nF, depending on the specific application and noise requirements. A larger input capacitance can help filter out noise, but may also increase the startup time.
The TRSF3232ECDWR is rated for operation up to 125°C, but it's essential to consider the derating of the device's performance and reliability at high temperatures. Consult the datasheet and application notes for guidance on high-temperature operation.
Follow proper PCB design and layout practices, use shielding and filtering as needed, and ensure that the device is properly decoupled and bypassed. Consult the application note SLVAE03 for more information on EMC considerations.
