GaN + Digital Control + High-Performance Magnetics
Designing an Ultra-thin, Highly Efficient (>97%), Multilevel DC-to-DC Converter

Renee Yawger, Director of Marketing

GaN-based solutions coupled with digital control and high-performance magnetics can increase efficiency, shrink the size, and reduce system costs for high density computing applications like ultra-thin laptops and high-end gaming systems.

As computers, displays, smart phones and other consumer electronics systems have become thinner and more powerful over the past decade, there is increasing demand for addressing the challenge of thinner solutions while extracting more power out of limited space.

The multilevel converter is an exceptional candidate to shrink the size of the magnetic components and achieve high efficiency in a compact solution. Leveraging the advantages of eGaN® FETs, such as small size and low loss, further enhances the performance of a multilevel solution. This blog will evaluate the EPC9148, a 48 V to 20 V, 250 W three-level converter using eGaN FETs and digital control which achieves a peak total system efficiency of 97.8% and only 4.1 mm component height.
