Cosel recommends a multi-layer PCB with a large ground plane and thermal vias to dissipate heat. A minimum of 2oz copper thickness is recommended. For thermal management, a heat sink with a thermal interface material (TIM) is recommended, and the device should be mounted on a metal core PCB or a heat sink with a thermal conductivity of at least 1 W/m-K.
To ensure EMC, Cosel recommends using a shielded enclosure, keeping the DC-DC converter away from sensitive circuits, and using a common-mode choke or ferrite beads on the input and output lines. Additionally, a 10nF capacitor can be added between the input and output grounds to reduce noise.
The derating curve for the MGW152412 is typically provided in the datasheet. However, as a general guideline, the output power derates by 1.5% per degree Celsius above 50°C. For example, at 70°C, the output power would be approximately 85% of the rated power.
Yes, the MGW152412 can be used in a redundant or parallel configuration. However, it's essential to ensure that the devices are synchronized and that the output voltages are matched to prevent current imbalance. Cosel recommends using a master-slave configuration with a synchronization signal to ensure proper operation.
The MTBF of the MGW152412 is typically calculated based on the component failure rates and is provided in the datasheet. However, as a general guideline, the MTBF of the MGW152412 is approximately 1.5 million hours at 40°C, and 1 million hours at 50°C, based on MIL-HDBK-217F calculations.
