VI-274-IW

Product Overview

The Vicor Corporation VI-274-IW is an isolated full-brick DC-DC converter that provides a single 48 V output from a 100 V to 375 V input. It is rated for 100 W and 2.08 A output current, with 3 kV isolation between input and output. The module uses through-hole mounting and is specified for operation from -40°C to 85°C, with 90% efficiency. Built-in protection features include over-current, over-temperature, over-voltage, and short-circuit protection, making it suitable for board-level power architectures that require galvanic isolation and a 48 V board-level rail.

Key Features

• Isolated module with a single 48 V output and 2.08 A maximum output current
• Input range of 100 V to 375 V for conversion to a 100 W output
• 3 kV input-to-output isolation for board-level power separation
• Through-hole full-brick package measuring 4.60 in L x 2.40 in W x 0.50 in H (116.8 mm x 61.0 mm x 12.7 mm)
• Operating temperature range of -40°C to 85°C with 90% efficiency
• Protection functions including OCP, OTP, OVP, and SCP

Applications

• Commercial information technology equipment requiring an isolated 48 V board-level supply
• Embedded systems with a high-voltage DC input that need a 48 V supply
• Test and measurement platforms using isolated board-level power conversion

Design & Procurement Notes

Designers should confirm that the system input remains within 100 V to 375 V and that the 48 V load does not exceed 2.08 A or 100 W. The 3 kV isolation rating supports separated input and output domains, while OCP, OTP, OVP, and SCP provide protection functions that should be coordinated with system-level fault handling. The full-brick through-hole package requires board area and clearance for its 116.8 mm x 61.0 mm x 12.7 mm dimensions, and layout should account for thermal management within the -40°C to 85°C operating range. For procurement, specify VI-274-IW to ensure the 48 V, 100 W full-brick configuration.
