Vicor recommends a 4-layer PCB with a solid ground plane, and thermal vias under the module to dissipate heat. A minimum of 2 oz copper thickness is recommended. Additionally, a heat sink or thermal interface material can be used to further improve thermal performance.
To ensure reliable start-up and shutdown, Vicor recommends a soft-start circuit to limit inrush current, and a voltage supervisor to monitor the input voltage. Additionally, a minimum input capacitance of 10uF is recommended to filter out noise and ensure stable operation.
The V28C12T100BG can tolerate up to 10% input voltage ripple and noise, but Vicor recommends keeping it below 5% to ensure optimal performance and reliability.
Yes, the V28C12T100BG is designed for high-reliability applications and can operate up to 100°C ambient temperature. However, Vicor recommends derating the output power and consulting with their application engineers for specific guidance on high-reliability applications.
The V28C12T100BG has built-in thermal monitoring and fault detection. Vicor recommends using the module's temperature sense pin to monitor the temperature, and the fault pin to detect over-temperature, over-voltage, and under-voltage conditions.
