320W Isolated and Regulated 48-Vdc Input DC-DCs

December 14, 2016 by Jeff Shepard

Aimed at a variety of applications, including Industrial and Communications, Vicor has added three new 48V input nominal modules (36- to 75-Vdc range) in a 3414 VIA package (3.38 x 1.40 x 0.37 in). These converters have output voltages of 12-, 24-, and 48-Vdc, with power levels of 320W, achieving a power density up to 183 W/in³.

The DCM in a VIA Package is a ruggedized modular dc-dc converter operating 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 functional integration by incorporating 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.

DCMs include an integrated heat sink and are offered in three temperature grades: C grade rated for -20 to +100 degrees C; T grade rated for -40 to +100 degrees C; and M grade rated for -55 to +100 degrees C (available soon). Both analog and digital communications are offered and PMBus will be offered in the future. These dc-dc converters feature an integrated EMI and transient filter, MIL-STD-461 compliance with an external filter.
