A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the device, and use short, wide traces for the high-current paths.
Ensure that the output voltage is within the specified range, and the input voltage is above the minimum required voltage. Also, use the recommended output capacitor value and ensure that the feedback resistors are within the specified range.
The maximum ambient temperature that the LTM9011IY-14#PBF can operate in is 125°C. However, the device's performance may degrade at higher temperatures, and the maximum junction temperature should not exceed 150°C.
Yes, the LTM9011IY-14#PBF is suitable for high-reliability applications. It is manufactured using a high-reliability process, and it has undergone rigorous testing to ensure its performance and reliability.
Start by checking the input voltage, output voltage, and current. Verify that the device is properly connected and that the feedback resistors are correct. Check for any signs of overheating, and ensure that the device is operated within its specified parameters.
