MI-221-IW Description

Short technical summary and product information.

The Vicor MI-221-IW is an isolated DC-DC converter from the MI-200 family, designed for distributed power architectures. It provides a single regulated 12V output at up to 8.3A, delivering 100W of output power with a typical efficiency of 90%.

 

This converter operates over an input voltage range starting at 18V and includes protection features such as remote on/off, overcurrent protection (OCP), overtemperature protection (OTP), and overvoltage protection (OVP). The overtemperature shutdown is set at 95°C typical, with automatic restart upon power recycling.

 

Housed in a full brick package (106.7mm x 61.0mm x 12.7mm) with through-hole mounting, the MI-221-IW is suitable for commercial ITE (Information Technology Equipment) applications. Its operating temperature range spans -40°C to 85°C.
