DCM3717 targets data centres to deploy 48V for legacy 12V loads

Customers in data centre, automotive and industrial markets can quickly deploy high-performance 48V power delivery for legacy 12V loads while achieving significant power-system size, weight and efficiency benefits, using the DCM3717, says Vicor.

The regulated 48V to 12V converter operates from a 40 to 60V safety extra low voltage (SELV) input and is non-isolated. It provides a regulated output with a range of 10 to 13.5V, a continuous power rating of 750W and a peak efficiency of 97.3 per cent. It is provided in a surface mount converter in package (SM-ChiP) which measures 37 x 17 x 7.4mm.

The DCM3717 supports the recent Open Compute Project (OCP) Open Rack Standard V2.2 for distributed 48V server backplane architectures and the LV148 specification (48V automotive standard) for pure electric and hybrid vehicles. It also provides a regulated 48V to 12V option for downstream legacy 12V multiphase point of load (PoL) converters.

Customers who do not require regulation of the 12V supply can take advantage of the Vicor NBM2317, a 750W non-regulated 48V to 12V converter which is available in a smaller 23 x 17 x 7.4mm SM-ChiP. This has 40 per cent higher power density and higher efficiency at 97.5 per cent, said Vicor.

Vicor designs, develops, manufactures and markets modular power components and complete power systems based upon a portfolio of patented technologies.

Headquartered in Andover, Massachusetts, USA, Vicor sells its products to the power systems market, including enterprise and high-performance computing, industrial equipment and automation, telecommunications and network infrastructure, vehicles and transportation, aerospace and defence.
