Aimtec recommends a PCB layout with a solid ground plane, minimal thermal resistance, and a heat sink attached to the module. A thermal interface material (TIM) with a thermal conductivity of 1-2 W/m-K is recommended between the module and heat sink.
To ensure reliability and longevity, operate the module within the recommended temperature range (–40°C to +85°C), avoid thermal shocks, and ensure proper cooling. Also, follow the recommended derating curves for output power and voltage.
The maximum allowable capacitance for the output filter capacitors is 10 μF. Exceeding this value may cause instability or oscillations in the output voltage.
Yes, the AM2D-0518SZ can be used in a redundant or parallel configuration, but it's essential to ensure proper synchronization and current sharing between modules to avoid instability or damage.
Aimtec recommends a fuse rating of 2-3 A, slow-blow type, to provide adequate overcurrent protection without compromising the module's performance.
