The recommended PCB layout for optimal thermal performance involves using a 2-ounce copper layer, keeping the thermal vias as close to the device as possible, and using a solid copper pour on the top and bottom layers to dissipate heat efficiently.
-
To ensure stable operation with a high-input voltage, it's essential to follow the recommended input capacitor selection, use a suitable input filter, and ensure the device is properly decoupled. Additionally, consider using a voltage clamp or transient voltage suppressor to protect the device from voltage spikes.

Yes, the APT6015JN is suitable for high-reliability and aerospace applications. It's manufactured using a qualified process, and the device is screened to meet the requirements of MIL-PRF-19500. However, it's essential to consult with the manufacturer and follow the recommended screening and testing procedures for these applications.
-
To troubleshoot oscillations or instability issues, start by verifying the PCB layout and ensuring that the input and output capacitors are properly selected and placed. Check for any signs of overheating, and verify that the device is properly decoupled. Use a scope to analyze the input and output waveforms, and consult the application notes and datasheet for guidance on stability analysis and compensation techniques.
