GaN Talk Blog

The EPC91106 evaluation board is an advanced synchronous buck and boost converter, designed to deliver high power density in a compact form. Equipped with the 100V-rated, 11 mΩ RDS(on) EPC23104 eGaN® IC, this evaluation board provides a high-performance, space-saving solution for diverse applications. In this post, we’ll explore the design, key features, performance metrics, and experimental validation of the EPC91106, providing insights into its potential applications and suitability for power management solutions.

Modern displays, such as laptops and PC monitors, typically require a low power boost converter. In this application, the screen intensity is low to moderate and the converter is operated at light load most of the time, so the light-load efficiency is very important. The low switching loss of eGaN FETs can help address this challenge. This GaN Talk will examine the design of a 12 V to 60 V, 50 W DC/DC power module with low temperature rise using eGaN FETs in the simple and low-cost synchronous boost topology.
