V28C3V3M50BG3

Product Overview

The V28C3V3M50BG3 from Vicor Corporation is an isolated module DC-DC converter in the MICRO (50W) series, intended for board-mount power conversion. It provides a single 3.3 V output at up to 15.15 A from a 9 V to 36 V input, with 50 W output power. The converter offers 3 kV input-to-output isolation and uses a through-hole Quarter Brick package measuring 2.28 in L x 1.45 in W x 0.62 in H (57.9 mm x 36.8 mm x 15.7 mm). It includes overvoltage protection and undervoltage lockout, operates from -55°C to 100°C, and has an efficiency of 71.4%.

Applications

• Commercial information technology equipment requiring an isolated 3.3 V board supply
• Board-level power rails that need isolation from a 9 V to 36 V source
• Through-hole 50 W DC power conversion in Quarter Brick layouts

Design & Procurement Notes

Design and procurement should confirm that the 9 V to 36 V input range matches the system supply and that the 3.3 V, 15.15 A output can be routed to the load without exceeding the 50 W output power limit. The 3 kV isolation specification should be reflected in PCB creepage, clearance, and component layout, while the through-hole Quarter Brick package requires mechanical fit and mounting-hole verification. OVP and UVLO should be considered in protection design, and thermal management should account for the 71.4% efficiency and the -55°C to 100°C operating range.
