Isolated DC-DC converters

7 September 2016 Power Electronics / Power Management

Vicor released four additional DC-DC converters that are deployed in the rugged, chassis-mountable versions of its DCM family of isolated, regulated DC-DC converters. These new products extend the family by adding two 270 V and two 28 V nominal products.

The new 270 V models accept a 160 – 420 V input, and source up to 500 W to either a 12 V or 28 V output. The new 28 V variants accept a 16 – 50 V input, and source 180 W to a 5 V output or 320 W to a 15 V output. Typical applications include the industrial and process control markets, distributed power, ATE, communications, defence/aerospace, semiconductor manufacturing equipment and transportation.

The DCM in a VIA package is an isolated, regulated DC-DC converter, operating from an unregulated, wide range input to generate an isolated and regulated output. With its high-frequency zero-voltage switching (ZVS) topology, the converter consistently delivers high efficiency across the input line range. The DCM provides tight output voltage regulation and offers a secondary-referenced control interface for trim, enable and remote sense operation.
