TPS28225D   8 引脚高频 4A 吸入电流同步 MOSFET 驱动器

illustrate

 

TPS28225与TPS28226的是N沟道免费与自适应死区时间控制驱动功率MOSFET高速驱动程序。 这些驱动程序优化,在高电流一相和多相直流到直流转换器的各种用途。 该TPS28225 / 6是一个解决方案,提供高效率,体积小,低EMI emmissions。

其性能达到达8.8 10V栅极驱动电压,14 ns的自适应死区时间控制,14 ns的传播延迟和高电流2 -阿源和4甲汇驱动功能。 0.4 - 针对较低栅极驱动阻抗可使功率MOSFET的栅极低于阈值,并确保在高dV / dT相位节点转换没有贯通电流。 自举电容器内部二极管充电允许N沟道MOSFET的使用半桥配置。
