Dc/dc converters in high-density ChiP packaging

摘要

Vicor announces the expansion of its DCM series of dc/dc converters using the Converter housed in Package (ChiP) component format. 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. Aimed at a variety of applications, including UAV, ground vehicle, radar, transportation, and industrial controls, four new 30-V input nominal modules (9- to 50-V range) are offered in a 3623 ChiP package (1.52 × 0.90 × 0.29 in.). These converters have output voltages of 5,24,28, and 48 V and power levels up to 160 W, with a power density up to 404 W/in3. Also announced is a 28-V input nominal module (16- to 50-V range) in a 3623 ChiP package with a 3.3-V output at 120 W, a 375-W module with a nominal input voltage of 275 V (120-420 V) and 12-V output in a 4623 ChiP package, and a 270-V input nominal module (160-420-V range) in a 4623 ChiP package with a 48-V output at 500 W (1.89 × 0.90 × 0.29 in.), achieving a power density of 1,014 W/in~3.
