More Power, Less Space with New ABB DecaDLynx II Voltage Regulator

ABB DecaDLynx II Voltage Regulator

Aug 12, 2021

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.

“Today’s data-hungry applications – such as cloud computing, artificial intelligence, 5G, the Industrial Internet of Things (IIoT), and high-speed networking applications – require massive computational power,” said Vesa Jokitulppo, senior product manager at ABB Power Conversion. “To ensure there is enough room on the printed circuit board for the computing horsepower these applications need, concessions often have to be made. However, by shrinking the footprint of power components, and increasing their power densities, this premium board space can be reserved for even higher levels of computing capacity.”

The new DJT090 DecaDLynx II power modules can accommodate input voltages ranging from 7.0 to 14.4 volts (V) DC, with precisely regulated, programmable output voltages of 0.50V to 2V. The power supplies can be linked in parallel with up to eight units to achieve a maximum output current of 720A.

Additional features of the DecaDLynx II non-isolated, high-density voltage regulators include:

• Advance digital controls and monitoring to create “black box” fault detection for advanced diagnostics.

• 88.5 percent high-efficiency power conversion from 12V input to 1.2V output.

• Provide full rated power of 90A at typical operating conditions (12V input, 0.8V output, 200 linear-feet-per-minute airflow, and 75 degrees C ambient temperature).

• Improved time to market, field reliability and seamless design integration with full testing and built-in IPC9592-qualified modules

• Low transient and ripple attributes to meet load input voltage requirements.

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.

“In ASICs and high-current FPGA processors – for example – which continue to shrink in size, we can digitally configure our power converters with built-in PMBus* controls to further free up space for board designers. This helps to enhance end-solution functionality and capability,” Jokitulppo added.

Power engineers also can leverage ABB’s Power Module Wizard and Digital Power Insights tools to configure the modules to their specific needs.
