Vicor recommends a 4-layer PCB with a solid ground plane on the bottom layer, and a thermal relief pattern on the top layer to ensure good thermal conductivity. A minimum of 2 oz copper thickness is recommended.
To ensure reliable start-up, Vicor recommends a soft-start circuit to limit the inrush current, and a minimum input capacitance of 10uF to ensure stable output voltage.
The maximum allowed input voltage ripple is 10% of the nominal input voltage, with a maximum deviation of ±5% from the nominal input voltage.
Yes, the DCM3623T50T0680T70 can be used in a redundant configuration, but it requires a diode ORing circuit to ensure that the output voltage is not short-circuited in case of a failure.
Vicor recommends a common-mode choke and a differential-mode capacitor to filter out electromagnetic interference (EMI). The recommended values are 10uH and 100nF, respectively.
