RECOM provides a recommended PCB layout in their application note AN-20, which includes guidelines for thermal vias, copper thickness, and component placement to ensure optimal thermal performance.
To ensure reliable start-up and operation with a high-capacitance output filter, RECOM recommends adding a soft-start circuit or a pre-charge resistor to limit the inrush current and prevent voltage overshoot.
According to RECOM, the maximum allowed voltage deviation on the input pins is ±10% of the nominal input voltage, but it's recommended to keep the deviation within ±5% to ensure reliable operation and minimize stress on the converter.
The REC8-2405SRWZ/H2/A/M/SMD-R is rated for operation up to 85°C, but RECOM recommends derating the output power by 2.5% per degree above 70°C to ensure reliable operation and prevent overheating.
RECOM recommends using external OVP and UVP circuits, such as a voltage supervisor IC or a discrete circuit, to protect the converter and downstream components from voltage faults.
