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, Inc. (MPS), a leading company in high-performance power solutions, announced the launch of a new family of 48 V – 6V digital DC-DC power modules for 48 V Data Center Solutions, utilizing eGaN® transistors from Efficient Power Conversion (EPC) Corporation. These power modules target applications for high-density computing and data centers, artificial intelligence, machine learning, and multi-user gaming.
- 48 V – 6 V
- LLC 10:1
- 300 W
- 27 mm x 18 mm
- 1700 W/in3
The MPC1100-54-0000 is the first in the new product family that will include modules in an LLC topology that utilize eGaN FETs to achieve an overall efficiency above 97% in a footprint of only 27 mm x 18 mm x 6 mm for 48 V – 6 V conversion. A key advantage of 48 V – 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 to reduce the power distribution loss by 4x compared to the commonly used STC topology for 48V – 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 5 V gate operation that yields very low gate power consumption, ultra-low on-resistance, and low output capacitance charge.
