USB PD 和快速充電器

USB PD 和快速充電器

諸如 USB PD/QC 3.0 等快速充電器通訊協定,可將手機的充電時間從持續一整夜大幅縮短至 30 分鐘以內。使得充電更為便捷,讓使用者幾乎能不間斷地存取行動裝置。

USB PD 已成為行動裝置充電的全新標準。USB PD 的功率容量高達 100 W,讓使用者可採用單一充電器為手機、平板電腦以及筆記型電腦充電。

PowiGaN™ 是Power Integrations自行研發的氮化鎵(GaN)技術。在PI高度集成的離線反馳式開關IC中,PowiGaN開關替代一次側的傳統矽晶體管,從而降低開關損耗,和矽器件相比,PowiGaN產品可實現體積更小,重量更輕,效率更高的充電器、適配器和開架式電源。

基於PowiGaN的IC在整個負載範圍內的效率高達95%,在封閉式適配器應用中不需散熱片就可實現高達100W輸出功率。
