The Revolutionary GaN Power IC from Navitas
相对于微电子技术，电力电子技术的发展相对缓慢。电子产品的尺寸越来越小、性能越来越强，但与之配套的电源却很久没有实现大幅进步。不过，僵局很快就会被打破。总部位于美国加州El Segundo的Navitas公司（纳微半导体）研发的的GaN（氮化镓）功率集成电路技术将为电源技术带来一场革命。
Navitas GaN Power ICs Enable Minimised Power Adapter
納微(Navitas)半導體宣佈推出世界上最小的65W USB-PD(Type-C)電源轉換器參考設計，以跟上過去十年來筆記型電腦在更小尺寸和更輕重量兩方面的顯著改變。這高頻及高效的AllGaN功率IC，可縮小變壓器、濾波器和散熱器的尺寸、減輕重量和降低成本。相比現有的基於矽的設計，需要98-115cc（或6-7 in3）和重量達300g，基於AllGaN功率IC的65W新設計體積僅為45cc（或2.7 in3），而重量僅為60g。
Only one-fifth of the size of others, GaN power IC enables notebook battery to get even slimmer
近日，纳微 (Navitas) 半导体推出世界上最小的65W USB-PD (Type-C) 电源适配器参考设计NVE028A。市场上现有的基于硅功率器件的适配器尺寸约98-115cc，重量达300g，凭借Navitas 的GaN功率IC AllGaN在功率密度上的显著优势，这一方案的尺寸仅为传统适配器的1/5。

GaN Power IC Enables The World’s Smallest Power Adapter For Laptops; Navitas Is The First In This Area
同事张小姐是一位肩周炎患者，但工作性质决定她必须每日外出拜访客户，于是听到她最多的抱怨便是电脑太重，事实上除了电脑之外，电源适配器“功不可没”，相信很多人和张小姐一样有同感，走路累的时候恨不得把电脑一块儿扔了
GaN Power IC is high efficient, and the 65W power adapter design is well established and smaller
氮化鎵(GaN) MOSFET已經開始在電源應用發酵。不過，受限於驅動器、控制器仍採用CMOS製程，因此氮化鎵MOSFET的威力還無法完全釋放。為此，電源晶片新創公司Navitas以全氮化鎵電源晶片作為挑戰題目，並已成功開發出整合電源管理電路、驅動器與MOSFET的晶片解決方案。此外，該公司為了展示全氮化鎵方案的優勢，還推出外觀尺寸僅2.7立方英吋，重量60公克，輸出功率卻可達65W的USB-PD電源參考設計。...
