XP Power recommends a PCB layout with a large copper area for heat dissipation, and a thermal management system with a heat sink and thermal interface material to keep the junction temperature below 125°C.
To ensure EMC, XP Power recommends following the layout and grounding guidelines in the datasheet, using a metal enclosure, and adding EMI filters and shielding as necessary to meet relevant EMC standards.
The derating curve for JTB0548S05 is typically provided in the datasheet or can be obtained from XP Power's application notes. It shows the reduction in output power as a function of temperature, and engineers should use this curve to ensure the module operates within its specified ratings.
While the JTB0548S05 is designed to meet standard vibration and shock tests, XP Power recommends consulting their application notes and performing additional testing to ensure the module meets the specific requirements of the target environment.
XP Power recommends using low-ESR capacitors with a voltage rating that meets or exceeds the input and output voltage ratings of the module. The specific capacitor values and types may vary depending on the application, and engineers should consult the datasheet and application notes for guidance.
