With IT and networking technologies continuing to pack more features and processing capacity into smaller packages, printed circuit and wired board space is at more of a premium than ever before. For power engineers and board designers, that can mean less board space available for required power components. ABB is helping to free up valuable board space with its new, high power density 90-amp (A) DecaDLynx II power supply. The DC-DC converter fits into a 327-millimeter (mm)2 footprint and achieves a 178-A/in2 power density – one of the highest available today.
The new DJT090 DecaDLynx II power modules can accommodate input voltages ranging from 7V to 14.4V DC, with precisely regulated, programmable output voltages of 0.5V to 2V. The power supplies can be linked in parallel with up to eight units to achieve a maximum output current of 720A.
ABB’s DecaDLynx II power modules meet the rigorous power density and efficiency requirements of demanding applications such as high-speed switches and routers, artificial intelligence processors, tight voltage rails for high-performance processors and in application-specific integrated circuits (ASICs), high-current field-programmable gate array (FPGA) processors, ARM processors, test and measurement devices, and data storage equipment.
