LMG5200 48V to 1V/40A single-stage converter reference design

PMP4497

Overview

PMP4497 is a GaN-based reference design solution suitable for Vcore applications such as FPGA and ASIC. With high integration and low switching losses, the GaN module LMG5200 enables high-efficiency single-stage 48V to 1.0V solutions, replacing traditional two-stage solutions. This reference design demonstrates the GaN performance and system advantages of this solution compared to two-level solutions. Low cost ER18 flat PCB transformer embedded on board. This reference design is compact in size (45mm*26mm*11mm). Further size reduction can be achieved by optimizing frequency and components.
