Vicor recommends a 4-layer PCB with a solid ground plane and thermal vias to ensure optimal thermal performance. A minimum of 2 oz copper thickness is recommended for the top and bottom layers.
To ensure reliable start-up, Vicor recommends a soft-start circuit to limit the inrush current. A minimum of 10uF capacitance on the input and output is also recommended to filter out noise and ensure stable operation.
The maximum allowed input voltage ripple for the DCM3623T50M31C2M70 is 10% of the nominal input voltage. Exceeding this limit may affect the reliability and performance of the module.
The DCM3623T50M31C2M70 is rated for operation up to 100°C ambient temperature. However, Vicor recommends derating the output power by 1% for every 1°C above 80°C to ensure reliable operation.
Vicor recommends a common-mode choke and a differential-mode filter capacitor to minimize EMI emissions. The specific component values and configuration will depend on the application and regulatory requirements.
