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 operation.
The maximum allowed input voltage ripple is 10% of the nominal input voltage, or 1.5V peak-to-peak, whichever is smaller.
Yes, the DCM3623T50T31A6T70 is rated for operation up to 100°C ambient temperature, but derating is required above 85°C. Consult the datasheet for derating curves.
Vicor recommends checking the input voltage, output voltage, and output current to identify the source of the issue. Consult the datasheet and application notes for troubleshooting guidelines.
