Panasonic recommends a 4-layer PCB with a solid ground plane, and a separate power plane for the DC-DC converter. The input and output capacitors should be placed close to the IC, and the feedback resistors should be placed close to the output capacitor.
To ensure stability, the output capacitor should be a low-ESR type with a value between 10uF to 22uF. The feedback resistors should be chosen to provide a stable feedback loop, and the input voltage should be within the recommended range.
The maximum ambient temperature for the DRC9114W0L is 85°C, but it can be derated to 70°C for high-reliability applications.
Yes, the DRC9114W0L is designed to withstand vibrations up to 10G, but it's recommended to follow Panasonic's guidelines for vibration testing and to ensure proper PCB mounting and soldering.
Troubleshooting should start with checking the input voltage, output voltage, and feedback loop. Verify that the PCB layout and component values match the recommended design. Use an oscilloscope to check for oscillations or noise on the output, and consult Panasonic's application notes and technical support for further assistance.
