Modular 500W DC/DC converters take 48/300V to 28V output,

February 08, 2017 // By Graham Prophet
Vicor has added to its range of DCM DC/DC converters in its VIA package. The DCM in VIA package is a ruggedized modular DC-DC converter that operates from an unregulated, wide range input, to generate an isolated and regulated high efficiency output, while claiming much higher power densities than alternative products.

The new DCMs offer power system engineers enhanced functionality of EMI filtering, transient protection, inrush current limiting, and a secondary-referenced control interface for trim, enable and remote-sensing. Configurations are available for both on-board mounting and for chassis mounting.

 

Aimed at a variety of applications, including industrial and communications, the two added models comprise; a 48V input nominal module (36-75V range) in a 3414 VIA package (3.38 x 1.40 x 0.37 in) with a 28V/320W output; and a 300V input nominal module (200-420 range) in a 3714 VIA package (3.75 x 1.40 x 0.37 in) with a 28V/500W output, achieving a power density up to 257 W/in ³.
