MPS & EPC Redefine DC/DC Power Conversion with 48V to 6V LLC Module Family for High-Density Computing and Datacenters

MPS MPC1100-54-0000

The combination of MPS (Monolithic Power Systems) controllers with ultra-efficient eGaN® FETs from EPC (Efficient Power Conversion) enable best-in-class power density of 1700 W/in3 in high-efficiency, low-cost LLC DC/DC conversion.

Monolithic Power Systems (MPS) announced the launch of a new family of 48 V to 6 V digital DC/DC power modules for 48 V 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 - MPC1100-54-0000

MPS’s MPC1100-54-0000 is the first controller in a product family that will include 48 V to 6 V LLC modules that utilize eGaN FETs to achieve an overall efficiency above 97% in a small 27 mm × 18 mm × 6 mm footprint. A key advantage of 48 V to 6 V 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 48 V to 12 V 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 5 V gate operation that yields very low gate power consumption, ultra-low on resistance, and low output capacitance charge.

With power levels ranging from 300 W to 1000 W, 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.
