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 is also recommended.
Ensure the input voltage rises monotonically to the minimum specified start-up voltage (typically 90% of nominal input voltage). A soft-start circuit can also be used to reduce inrush current.
The maximum allowed capacitance on the output is 10,000uF. Exceeding this value may cause instability or oscillation.
Yes, the AHM250PS19T can be used in a redundant configuration, but ensure that the modules are synchronized to prevent output voltage oscillations.
The recommended fuse rating for the input is 5A slow-blow or 3A fast-acting, depending on the application's inrush current requirements.
