EML15US12-E Frequently Asked Questions (FAQs)

XP Power recommends a PCB layout with a large copper area for heat dissipation, and a minimum of 2oz copper thickness. A thermal via array under the module can also improve heat dissipation.
To ensure reliable start-up, XP Power recommends a soft-start circuit or an NTC thermistor in series with the input voltage to limit the inrush current. Additionally, a bulk capacitor at the input can help to reduce voltage droop during start-up.
The maximum allowable capacitance on the output is 47uF. Exceeding this value may cause instability or oscillation in the module.
Yes, the EML15US12-E can be used in a redundant configuration, but it's essential to ensure that the modules are synchronized to prevent current fighting. XP Power recommends using a diode ORing circuit or an external ORing controller to achieve this.
The derating curve for the EML15US12-E is typically 2.5% per degree Celsius above 40°C. This means that for every degree above 40°C, the output power should be derated by 2.5% to ensure reliable operation.
