Vicor DCM in ChiP package expands enhanced output voltage regulation models
Vicor has added 25 devices to its family of DC/DC converter modules (DCMs) with tighter output voltage regulation of ± one per cent. With what are described as unrivalled power densities of 1,032W/in3, the new series allows engineers to drive loads requiring tighter regulation with minimal additional circuitry or downstream components, explains Vicor.
The DCM ChiP (Converter housed in Package) is a DC/DC converter module that operates from an unregulated, wide range input to generate an isolated, regulated DC output. With its high frequency zero-voltage switching (ZVS) topology, the DCM converter consistently delivers high efficiency across its entire input voltage range.
The DCMs can be used across defence and industrial applications that require tighter output voltage regulation, for example in unmanned aerial vehicles (UAVs), ground vehicle, radar, transportation and industrial controls.
The DCM ChiPs are available in M-grade, which can perform at temperatures as low as -55 degrees C. They are available with nominal voltages of 28, 30, 42, 48, 100, 270, 275 and 300V and in the 3623 ChiP, measuring 1.5 x 0.8 x 0.2-inch or 38 x 20 x 5.0mm) or the 4623 ChiP package for the 270, 275 and 300V models. Outputs range from 3.5, 5.0, 12, 15, 24, 28, 36 and 48V, depending on the DCM. Input voltages also vary depending on the model.
