Vicor recommends a 4-layer PCB with a solid ground plane and thermal vias to dissipate heat. A minimum of 2 oz copper thickness is recommended. Additionally, a thermal interface material (TIM) should be used between the module and the heat sink to ensure good thermal conductivity.
To ensure reliable start-up and shutdown, Vicor recommends a soft-start circuit to limit inrush current and a shutdown circuit to prevent voltage overshoot. Additionally, a minimum input capacitance of 10uF is recommended to ensure stable operation.
Vicor recommends derating the module's power rating by 1% per 1,000 feet above sea level and by 1% per 1°C above 40°C ambient temperature. This ensures reliable operation in high-altitude and high-temperature environments.
Yes, the V300B28M250BG can be used in a parallel configuration to increase power output. However, Vicor recommends using a current sharing circuit to ensure equal current distribution between modules and to prevent uneven stress on the components.
Vicor recommends using a pi-filter configuration with a common-mode choke and X-capacitors to minimize EMI. The filter should be designed to meet the specific requirements of the application and the relevant EMI standards.
