CUI Devices recommends a 4-layer PCB with a solid ground plane, and a separate layer for the power traces to minimize noise and EMI. Additionally, keep the input and output capacitors close to the module to reduce parasitic inductance.
Ensure good airflow around the module, and consider adding a heat sink if the ambient temperature exceeds 40°C. Also, avoid blocking the ventilation holes on the module to prevent overheating.
CUI Devices recommends using capacitors with a maximum value of 10uF for the input filter and 22uF for the output filter to prevent oscillation and ensure stability.
Yes, the PD-40V can be used in redundant or parallel configurations, but it's essential to ensure that the modules are synchronized and properly connected to avoid any potential issues.
Check the input voltage, output load, and PCB layout for any issues. Verify that the input and output capacitors are within the recommended values, and ensure that the module is properly soldered and connected. If the issue persists, contact CUI Devices' technical support for further assistance.
