Vicor recommends a 2-layer PCB with a solid copper plane on the bottom layer for heat spreading, and a minimum of 2 oz copper thickness. Additionally, a thermal via array under the module can help to dissipate heat.
Vicor recommends following the recommended PCB mounting and screw torque specifications, and using a conformal coating to protect the module from moisture and contaminants. Additionally, the module can be potted or encapsulated for added protection.
The VI-MU3-EQ can tolerate up to ±10% deviation from the nominal input voltage without affecting performance or reliability. However, it's recommended to consult with Vicor's application engineers for specific guidance on input voltage tolerance.
Yes, the VI-MU3-EQ can be paralleled to increase output power, but it's essential to follow Vicor's guidelines for parallel operation, including using identical modules, ensuring proper synchronization, and implementing a current-sharing scheme.
Vicor recommends using a common-mode choke and a differential-mode filter capacitor to minimize EMI emissions. The specific filter configuration may vary depending on the application and regulatory requirements, so it's recommended to consult with Vicor's application engineers for guidance.
