Description:The MJWI20 series is a new generation of high performance DC-DC converter modules setting a new standard concerning power density. The product offers fully 20W in a shielded metal package with dimensions of just 1.0"x1.0"x 0.4". All models provide ultra-wide 4:1 input voltage range and tight output voltage regulation. State-of the-art circuit topology provides a very high efficiency up to 89% which allows an operating temperature range of -40℃ to +85℃. Further features include remote On/Off, trimmable outpu
The recommended PCB layout involves placing the DC-DC converter near the input capacitors and output capacitors, with a solid ground plane and minimal thermal resistance. Thermal management involves providing adequate airflow, using a heat sink, and ensuring the ambient temperature is within the specified range.
To ensure EMC, use a shielded enclosure, keep the input and output cables short and twisted, and add EMI filters or common-mode chokes as needed. 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 1-2% per degree Celsius above 50°C to ensure reliable operation.
Yes, the MJWI20-24D15 can be used in a redundant or parallel configuration, but it's essential to ensure proper synchronization and current sharing between the units. Consult the manufacturer or a qualified engineer for specific guidance.
The MTBF is not explicitly stated in the datasheet, but it can be calculated using the failure rates of the individual components and the manufacturer's reliability data. As a rough estimate, the MTBF is typically in the range of 500,000 to 1,000,000 hours.
