Monolithic Power Systems, Inc. announced the launch of a new family of 48V to 6V digital DC/DC power modules for 48V Datacenter Solutions, utilizing eGaN® transistors from Efficient Power Conversion (EPC) Corporation. These power modules target applications for high-density computing and datacenters, artificial intelligence, machine learning, and multi-user gaming. MPS’s MPC1100-54-0000 is the first controller in a product family that will include 48V to 6V LLC modules that utilize eGaN FETs to achieve an overall efficiency above 97% in a small 27mmx18mmx6mm footprint. A key advantage of 48V to 6V front-end conversion includes the enabling of a high-frequency secondary stage that is small enough to be placed much closer to the xPU/ASIC/GPU; this reduces 4X the power distribution loss, compared to the commonly used STC topology for 48V to 12V conversion. For high-density server applications, record power density and efficiency can be achieved with simple, low-cost topologies, such as an LLC DC/DC converter. eGaN FETs are well-suited for LLC converters due to their combined low gate charge with 5V gate operation that yields very low gate power consumption, ultra-low on resistance, and low output capacitance charge. With power levels ranging from 300W to 1000W, these modules are scalable to accommodate a range of high-current and high-power applications. Customers can add up to three modules to address higher power requirements, or scale down to one or two modules for lower power requirements.
