Modular dc-dc converters sport 36-75-V and 200-420-V inputs

Vicor Corporation announced the expansion of its DCM series of DC-DC converters utilizing the VIA power packaging format.The DCM in a 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, with much higher power densities than competitive products. The new DCMs offer power system engineers a better BRICK with their 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, Vicor has added two new models:  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 300 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/in3.
