RECOM Power Inc recommends a PCB layout with a solid copper plane underneath the module to dissipate heat. Additionally, a thermal via array under the module can help to further reduce thermal resistance. It's also important to ensure good airflow around the module.
The RAC03-3.3SK/SMT-R module is certified to various safety standards, including UL60950-1, EN60950-1, and IEC60950-1. However, it's essential to ensure that the module is used within its specified operating conditions and that the system design meets the required safety standards. RECOM Power Inc provides a safety report and certification documents to support system-level certification.
RECOM Power Inc provides a derating curve in the datasheet, which shows the recommended output power reduction as a function of ambient temperature. For example, the module can deliver 3W at 25°C, but this reduces to 2W at 50°C and 1W at 70°C. It's essential to follow this derating curve to ensure the module operates within its safe operating area.
The RAC03-3.3SK/SMT-R module has built-in input voltage transient protection, but it's still important to ensure that the input voltage is within the specified range. For applications with high voltage transients or surges, additional external protection components, such as TVS diodes or varistors, may be required to protect the module.
The RAC03-3.3SK/SMT-R module has a built-in undervoltage lockout (UVLO) circuit that shuts down the module during input voltage brownout or dropout conditions. When the input voltage recovers, the module will automatically restart. However, it's essential to ensure that the system design can handle the module's shutdown and restart behavior.
