Panasonic recommends a 4-layer PCB with a solid ground plane, and a separate power plane for the input and output. The input and output capacitors should be placed as close as possible to the IC, and the feedback resistors should be placed close to the output pin.
To ensure stability, Panasonic recommends using a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Additionally, the input voltage should be well-regulated, and the output voltage should be decoupled with a capacitor.
The maximum ambient temperature for the AXT670124 is 85°C, but it can be derated to 70°C for high-reliability applications.
Yes, the AXT670124 is designed to withstand high-vibration environments, but it's recommended to follow Panasonic's guidelines for vibration testing and to ensure that the PCB is properly secured and mounted.
Panasonic recommends checking the input voltage, output voltage, and output current to identify the source of the issue. Additionally, checking the PCB layout, component values, and soldering quality can help identify potential problems.
