Regulated 48V to 12V DC-DC converter module hits 2kW
Vicor has developed a range of scalable DC-DC converter modules for 48V to 12V systems with a power density of 5kW/in3 up to 2kW.
The DCM3717 and DCM3735 non-isolated DC-DC power modules support 750W to 2kW in 48V power delivery networks (PDNs) that provide greater power system efficiency and power density compared to 12V systems.
The modules operate from a 40V to 60V input to generate a regulated output adjustable from 10V to 12.5V for industrial applications.
The DCM3717 family measures 37mmx17mmx5.2mm and has two power ranges, 750W and 1kW. The DCM3735 is wider at 37mmx35mm5.2mm with a 2kW output. The modules can also be used in parallel to rapidly scale system power levels and the 5.2mm low-profile SM-ChiP surface-mount package is thermally optimised to simplify thermal management system design.
As with other 48V power modules, the non-isolated DCM modules can be used in conjunction with the Vicor BCM high- voltage fixed-ratio bus converter family that converts from high voltage (800V and 400V) to 48V. Once a 48V bus is established, these modules can efficiently convert from 48V to a regulated 12V.
Industrial applications such as battery formation and test (BFT) and semiconductor automated test equipment (ATE) are moving to 48V PDNs. Some BFT implementations, for example, have been optimized to convert 12V to the battery cell load and cannot be readily re-engineered for 48V. Using the DCM3717/3735 DC-DC converter modules allow BFT systems engineers to preserve their existing investment by bridging 48V and 12V to create a high-performance 48V power delivery network.
The DCM3717S60E13G5TN1 (750W) and DCM3717S60D13K0TN1 (1000W) non-isolated DC-DC converter modules are available today, and the DCM3735S60D13L0TN1 (2000W) will be available later this year.
