Aimtec recommends a PCB layout with a solid copper plane underneath the module, and a minimum of 2 oz copper thickness to ensure good thermal conductivity. Additionally, a thermal via array under the module can help to dissipate heat more efficiently.
To ensure reliable start-up and operation with a high-capacitance output filter, Aimtec recommends adding a soft-start circuit to limit the inrush current during start-up. Additionally, the output voltage should be monitored and controlled to prevent overshoot or undershoot during start-up and transient conditions.
Aimtec recommends that the input voltage deviation should not exceed ±10% of the nominal input voltage to ensure reliable operation. Exceeding this limit may affect the module's performance, efficiency, and reliability.
The AM15E-4805SZ is rated for operation up to 80°C ambient temperature. However, derating may be necessary for temperatures above 60°C to ensure reliable operation. Aimtec recommends consulting the datasheet and application notes for specific guidance on high-temperature operation.
Aimtec recommends following a systematic approach to troubleshoot and debug issues, including checking the input voltage, output voltage, and current, as well as monitoring the module's temperature and output ripple. Additionally, consulting the datasheet, application notes, and seeking support from Aimtec's technical team can be helpful in resolving issues.
