VI-254-EU Frequently Asked Questions (FAQs)

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 relief pattern around the device's thermal pads is recommended to ensure good thermal conductivity.
Vicor recommends following the recommended PCB mounting and screw torque specifications, and using a conformal coating to protect the device from moisture and contaminants. Additionally, the device's thermal interface material should be securely attached to the heat sink to prevent thermal interface resistance increase due to vibration.
The maximum allowed capacitance on the output of the VI-254-EU is 1000uF. Exceeding this value may cause instability or oscillation in the converter.
Yes, the VI-254-EU can be used in a parallel configuration to increase power output. However, it is recommended to use a master-slave configuration with a single clock signal to ensure synchronization and prevent beat frequencies. Additionally, the output capacitors should be matched to ensure equal current sharing between the devices.
The recommended input fuse rating for the VI-254-EU is 5A slow-blow or 3A fast-acting. The fuse should be selected based on the maximum input current and the device's power rating.
