A good thermal design should include a solid ground plane, thermal vias, and a heat sink if necessary. The datasheet provides some guidelines, but a more detailed application note from TI provides additional guidance.
To ensure a stable output voltage, make sure to follow the recommended capacitor selection and placement guidelines, and use a low-ESR output capacitor. Additionally, ensure the input voltage is within the recommended range and the device is operated within its specified temperature range.
Exceeding the maximum junction temperature can lead to reduced lifespan, decreased performance, and potentially even device failure. It's essential to ensure proper thermal management and heat dissipation to prevent overheating.
While the LMR10520YSDE/NOPB is a high-performance device, it may not meet the specific requirements for high-reliability or aerospace applications. Engineers should consult with TI's application engineers and review the device's qualification data to determine its suitability for such applications.
To troubleshoot issues, start by reviewing the device's datasheet and application notes. Check the PCB layout, component selection, and thermal design. Use oscilloscopes and thermal imaging tools to identify the root cause of the issue. If necessary, consult with TI's technical support team for further assistance.
