Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good thermal design practices, such as using a solid ground plane, placing thermal vias under the device, and keeping the thermal path short and direct.
The input capacitor selection depends on the input voltage, output voltage, and desired ripple current. A general rule of thumb is to choose a capacitor with a voltage rating at least 1.5 times the input voltage, and a capacitance value that meets the recommended ripple current specification.
The TPS35AA17AGADDFR has a maximum ambient temperature rating of 85°C, but it's essential to consider the device's thermal performance and derate the output current accordingly to ensure reliable operation.
The TPS35AA17AGADDFR is an automotive-grade device, but it's essential to review the device's AEC-Q100 qualification and ensure it meets the specific requirements of your application. Additionally, consider the device's fault tolerance, diagnostic capabilities, and compliance with relevant industry standards.
The TPS35AA17AGADDFR has a built-in OVP feature, but it's essential to understand the OVP threshold and hysteresis to ensure proper implementation. Additionally, consider using external components, such as a voltage supervisor or a dedicated OVP IC, to provide additional protection and flexibility.
