PRODUCTION DATA.
LMG341xR070 GaN 功率级具有集成型驱动器和保护功能,可让设计人员在电力电子系统中实现更高水平的功率密度和效率。LMG341x 的固有优势超越硅 MOSFET,包括超低输入和输出电容值、可将开关损耗降低 80% 的零反向恢复以及可降低 EMI 的低开关节点振铃。这些优势支持诸如图腾柱 PFC 之类的密集高效拓扑。
LMG341xR070 通过集成一系列独一无二的特性提供传统共源共栅 GaN 和独立 GaN FET 的 替代产品 ,以简化设计,最大限度地提高可靠性并优化任何电源的性能。集成式栅极驱动器支持 100V/ns 开关(Vds 振铃几乎为零),低于 100ns 的限流可自行防止意外击穿事件,过热关断可防止热逃逸,而且系统接口信号可提供自监控功能。
