The recommended PCB layout for optimal thermal performance involves placing the module on a multi-layer PCB with a large copper area for heat dissipation. The copper area should be connected to a solid ground plane to ensure good heat conduction.
To ensure reliable start-up of the module, make sure to provide a soft-start circuit to limit the inrush current during power-on. Additionally, ensure that the input voltage is within the specified range and the input capacitance is sufficient to filter out noise and ripple.
The maximum allowed capacitance on the output is 10uF. Exceeding this value may cause instability or oscillation in the output voltage.
The RS3-2405D/H3 is rated for operation up to 80°C ambient temperature. However, derating may be necessary for high-temperature applications. Consult the datasheet for derating curves and consult with RECOM Power Inc for specific guidance.
To protect the module from input voltage transients, use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input. This will help absorb voltage spikes and ensure the module operates within its specified input voltage range.
