Description:The MA03 series is a range of isolated 3W DC-DC converter modules in a small SIP-package. There are 12 models available with 5V, 12V or 24VDC input. These products have a typical load regulation of 5.0% to 7.0% depending on model.
The recommended PCB layout involves placing the DC-DC converter near the power source, using a solid ground plane, and keeping the input and output capacitors close to the converter. For thermal management, ensure good airflow, use a heat sink if necessary, and avoid blocking the airflow around the converter.
To ensure EMC, use a metal shield around the converter, keep the input and output cables short and twisted, and add EMI filters or common-mode chokes if necessary. Also, follow the recommended PCB layout and grounding scheme.
The derating curve is not explicitly provided in the datasheet, but as a general guideline, the output power should be derated by 2-3% per degree Celsius above 50°C to ensure reliable operation and prevent overheating.
Yes, the MA03-05S05 can be used in a redundant or parallel configuration, but it's essential to ensure that the converters are synchronized and have a common control signal to prevent oscillations and ensure stable operation.
The maximum capacitance on the output of the MA03-05S05 is not explicitly stated, but as a general guideline, it's recommended to keep the output capacitance below 10uF to prevent stability issues and ensure reliable operation.
