The DCM format takes an unregulated, wide range input and generates an isolated DC output, using a high frequency zero voltage switching (ZVS) topology, with high efficiency across the input line range.

Four new 30V input nominal modules (9-50V range) come in a 3623 Chip package 38.7 x 22.8 x 7.3 mm (1.52 x 0.90 x 0.29 in.). These converters have output voltages of 5, 24, 28, and 48V, and power levels up to 160W, achieving a power density up to 404 W/in³. Also announced is a 28V input nominal module (16-50V range) in a 3623 ChiP package with a 3.3V output at 120W, a 375W module with a nominal input voltage of 275V (120-420V) and 12V output in a 4623 ChiP package, measuring 47.9 x 22.8 x 7.3 mm (1.89 x 0.90 x 0.29 in.), and a 270V input nominal module (160-420V range) also in a 4623 ChiP package with a 48V output at 500W, achieving a power density of 1,014 W/in³.

These introductions are aimed at a variety of applications, including UAV, ground vehicle, radar, transportation and industrial controls. Modular DCM converters and downstream DC-DC products support efficient power distribution, providing superior power system performance and connectivity from a variety of unregulated power sources to the point-of-load.
