Texas Instruments provides a recommended layout and placement guide in the datasheet, but it's essential to follow good PCB design practices, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths to reduce EMI and noise.
Choose input capacitors with low ESR (Equivalent Series Resistance) and high ripple current ratings. For output capacitors, select ones with low ESR, high capacitance, and a voltage rating that meets or exceeds the output voltage. The datasheet provides guidance on capacitor selection, but it's crucial to consider the specific application requirements and operating conditions.
The TPS65193RGER has a maximum ambient temperature rating of 85°C (185°F), but it's essential to consider the junction temperature (TJ) and ensure it doesn't exceed 150°C (302°F) during operation. The datasheet provides thermal resistance values to help estimate the junction temperature.
Yes, the TPS65193RGER is qualified for automotive and high-reliability applications. It meets the AEC-Q100 standard for automotive grade and is manufactured using a high-reliability process. However, it's essential to review the specific requirements of your application and ensure the device meets those needs.
Start by reviewing the datasheet and application notes for troubleshooting guidelines. Check the input voltage, output load, and PCB layout for any issues. Use oscilloscopes and thermal imaging cameras to monitor the device's behavior. If the issue persists, contact Texas Instruments' support team for further assistance.
