Vicor recommends a 4-layer PCB with a solid ground plane, and thermal vias under the module to dissipate heat. A thermal interface material (TIM) should be used between the module and the heat sink.
To ensure reliable start-up and shutdown, Vicor recommends a soft-start circuit to limit inrush current, and a shutdown circuit to discharge the output capacitors.
Input voltage transients can affect the DCM's performance and reliability. Vicor recommends using input voltage filtering and transient protection to ensure the DCM operates within its specified input voltage range.
Vicor recommends optimizing the DCM's performance by selecting the appropriate output voltage, adjusting the output capacitance, and optimizing the input voltage range for the specific application.
The DCM's power rating is derated at high temperatures. Vicor recommends derating the power rating by 1.5% per degree Celsius above 40°C to ensure reliable operation.
