CUI recommends a PCB layout with a solid ground plane, minimal trace lengths, and a decoupling capacitor (e.g., 10uF) between Vin and GND to ensure stable operation and minimize EMI.
To ensure reliable startup and shutdown, CUI recommends applying a soft-start circuit to the input voltage (Vin) and using a capacitor (e.g., 10uF) to filter the output voltage (Vout).
While the datasheet specifies an operating temperature range of -40°C to 85°C, CUI recommends derating the module's output power by 2.5% per degree above 60°C to ensure reliable operation in high-temperature environments.
Yes, the PQP1-D24-S5-M is designed to withstand vibrations up to 10G peak acceleration (10-2000Hz) and 2G peak acceleration (2000-5000Hz) according to IEC 60068-2-6. However, it's essential to ensure proper PCB mounting and secure the module to prevent damage.
To troubleshoot output voltage deviations or instability, check the input voltage, output load, and PCB layout. Ensure the input voltage is within the specified range, the output load is within the recommended range, and the PCB layout follows CUI's recommendations. Also, verify that the module is properly soldered and there are no signs of overheating.
