说明

TPS7H500x-SP 耐辐射加固保障高速 PWM 控制器系列。这些控制器提供的许多功能有助于设计面向太空应用的直流/直流转换器拓扑。控制器具有精密的内部基准 (0.613V +0.7%/-1%),可配置开关频率高达 2MHz。每个器件都提供可编程斜坡补偿和软启动功能。

TPS7H500x-SP 系列可通过 SYNC 引脚使用外部时钟来驱动,也可使用内部振荡器以用户编程的频率来驱动。此控制器系列为用户提供了各种选项,用于选择开关输出、同步整流功能、死区时间(固定或可配置)、前沿消隐时间(固定或可配置)和占空比限制。TPS7H500x-SP 系列中的每个器件均采用 22 引脚 CFP 陶瓷封装和 24 引脚 TSSOP 塑料封装。
