The partnership aims to drive common solutions in 48V power, specifically by establishing more common footprint blocks, improving supply chain efficiency, increasing design flexibility and reducing qualification processes during product development, and standardizing industry guidelines related to reliability and testing. 6.
As requirements per rack surpass 15 kW, the conduction losses of current across 12-V distribution architectures (which are four times the level of a 48-V bus) become unacceptable. This move towards 48-V systems has triggered rapid innovation in the design of board-level power supplies.
Telecom and wireless networks typically operate on –48 V DC power, but why? The short story is that –48 V DC, also known as a positive-ground system, was selected because it provides enough power to support a telecom signal but is safer for the human body while doing telecom activities.
Adoption of 48-V main bus architectures is driving down operating costs for leading data center operators by reducing distribution losses by a factor of 16 compared to 12-V power delivery. Building on this overall efficiency gain, engineers are fine-tuning down conversion topologies for board-level power delivery.
ADI will continue to respond to these and similar challenges by developing more –48 V DC high power conversion solutions designed for the 5G market while drawing on considerable expertise in power
