GS-EVM-CHG-100W: Charger Reference Design for Consumer Electronics


Note: Reference Design – Documentation Only

This GaN based 100W charger reference design provides a turn-key solution for the “100W, Multiple-ports” growing demand of consumer electronics industry. It displays outstanding performance, and best-in-class features of ultra-high-power density, high efficiency, and low surface temperature. This reference design is based on GaN Systems GaN transistors GS-065-011-1-L. The combined advantages of these transistors of low gate charge, low parasitic capacitor, and low on-state resistor lead to a more efficient system, demonstrating the benefits of GaN technology and meeting high power density without sacrificing the efficiency and thermal performance.
