RECOM recommends a PCB layout with a large copper area connected to the module's thermal pad to ensure good heat dissipation. A minimum of 2 oz copper thickness is recommended, and the copper area should be connected to a heat sink or a metal plate for further heat dissipation.
To ensure reliability in high-temperature environments, RECOM recommends following the derating curves provided in the datasheet, using a suitable heat sink, and ensuring good airflow around the module. Additionally, the module should be operated within the recommended temperature range and the input voltage should be kept within the specified limits.
RECOM recommends using a low-ESR ceramic capacitor with a value of 10-22uF, X7R or X5R dielectric, and a voltage rating of 50V or higher. The capacitor should be placed as close as possible to the module's input pins to minimize noise and ensure stable operation.
Yes, the RSO-4805SZ can be used in a redundant or parallel configuration, but RECOM recommends consulting with their application engineers to ensure proper design and implementation. The modules should be connected in a master-slave configuration, and the output voltage should be synchronized to prevent voltage differences between the modules.
The RSO-4805SZ has a built-in undervoltage lockout (UVLO) circuit that shuts down the module when the input voltage falls below 3.5V. When the input voltage recovers, the module will automatically restart. However, RECOM recommends implementing an external voltage supervisor or monitoring circuit to ensure a safe shutdown and restart sequence in critical applications.
