High-Density 120W to 500W Isolated DC-DCs

Vicor Corporation announced the expansion of its DCM series of dc-dc converters utilizing the Converter housed in Package™ (ChiP) power component format. Aimed at a variety of applications, including UAV, ground vehicle, radar, transportation and industrial controls, Vicor has added four new 30V input nominal modules (9- to 50-Vdc range) in a 3623 ChiP package (1.52 x 0.90 x 0.29 in). These converters have output voltages of 5-, 24-, 28-, and 48-Vdc, and power levels up to 160W, with a power density up to 404 W/in³.

Also announced is a 28V input nominal module (16- to 50-Vdc range) in a 3623 ChiP package with a 3.3V output at 120W, a 375W module with a nominal input voltage of 275V (120- to 420-Vdc) and 12V output in a 4623 ChiP package, and a 270V input nominal module (160- to 420-Vdc range) in a 4623 ChiP package with a 48V output at 500W (1.89 x 0.90 x 0.29 in), achieving a power density of 1,014 W/in³.

The DCM in a ChiP package is an isolated, regulated dc-dc converter, operating from an unregulated, wide range input to generate an isolated dc output. Leveraging a high frequency zero voltage switching (ZVS) topology, DCM converters consistently deliver high efficiency across the input line range. Modular DCM converters and downstream dc-dc products support efficient power distribution, helping to optimize power system performance and connectivity from a variety of unregulated power sources to the point-of-load.
