A recent Yole Intelligence market report has shown the continued growth of the GaN power device market, as well as the adoption of these devices in various applications ranging from consumer electronics to automotive applications. According to Yole intelligence, the GaN power market is expected to reach $1.6 billion by the year 2027, and the adoption of GaN devices in various consumer fast-charging applications is driving the growth of this segment.
GaN devices with better operating frequency and a smaller footprint than comparable Si devices will offer the advantages of decreased charging time, weight, and size for mobile chargers. Various designs have been chosen for integrating GaN devices in mobile chargers. Some manufacturers have opted for a GaN device with an external driver, while others use an integrated device with the Si-driver co-packaged. The cost of these devices can vary depending on the design choices, and a look into various cost components can lead to varied improvements and more adoption of GaN technologies.
In this report, Yole SystemPlus presents an overview of the state-of-the-art of GaN power devices used in various chargers to highlight differences in GaN HEMT design and their impact on device size and production cost. Six different chargers, from Samsung, Lenovo, Motorola, Apple, Xiaomi, and Dell, with power ratings ranging from 45W - 240 W, have been chosen, and the GaN devices in these chargers have been analyzed. The GaN transistors have a 650 / 700 V voltage rating and are packaged as either a discrete power die, a system-on-chip, or a system-in-package device.
This report provides detailed optical and SEM pictures of the GaN transistor device’s packaging and structure, down to the microscopic level of the HEMT design. Also included is a BOM analysis of two 45 W Samsung fast chargers with Power integrations (Si based) and Navitas (GaN-based) dies . The estimated manufacturing cost of the analyzed GaN devices and their selling prices are presented as well, along with physical, technological, and manufacturing cost comparisons between the analyzed devices.
