Vicor adds to high-power-density DCM DC/DC converter modules, to 600W

March 18, 2015 // By Graham Prophet
DC/DC converters in Vivor’s ChiP package address multiple markets with up to 76 W/cm³ power density.

The DCM converter module series now covers critical applications in Aerospace, EV/HEV, Rugged Systems, Industrial, and Telecom/Datacom. DCMs provide nominal input voltages of 24, 28, 48, 270, 290, and 300V with nominal outputs of 48, 36, 28, 24, 15, 12, and 5V and are available in packages rated for up to 600W.

DCMs can be coupled with Vicor FPA (factorised power) and/or ZVS (zero-voltage switching) regulators enabling full power solutions that deliver dense, efficient, and scalable source-to-load power. Designers can couple DCMs downstream with Vicor’s ChiP and SiP (system in package) point-of-load regulators, thereby enabling an integrated, complete power solution delivering dense, efficient, and scalable source-to-load power.

By using Vicor’s DC-ZVS topology within the DCM Series, 93% typical efficiency can be achieved, along with power density exceeding twice that of conventional DC-DC converters. With power density up to 76 W/cm³, DCMs enable engineers to optimise end systems for size, space, and weight. In addition, up to eight DCMs can be paralleled in an array without derating or additional circuitry. When configured in such an array, up to a 4.8 kW DC-DC solution can be achieved.

Vicor’s DCMs are available in two through-hole packages: a 4623 (46 x 23 mm) ChiP package capable of up to 600W and a 3623 (36 x 23 mm) ChiP package capable of up to 320W.

Pricing starts at $82.14 (1000).
