RECOM recommends a layout with a large copper area for heat dissipation, keeping the converter away from heat sources, and using thermal vias to connect the converter's thermal pad to the copper area.
To ensure reliable start-up and operation, RECOM recommends using a soft-start circuit or a ramp-up circuit to limit the inrush current, and selecting output capacitors with a low ESR to minimize 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% for optimal performance and reliability.
While the RB-053.3S is rated for operation up to 85°C, RECOM recommends derating the output power at high temperatures to ensure reliable operation. Consult the datasheet for derating curves and guidelines.
RECOM recommends using external OVP and UVP circuits, such as zener diodes and resistors, to protect the converter and downstream circuitry from voltage faults.
