说明

SN6507-Q1 是一款高压、高频推挽式变压器驱动器,以小尺寸解决方案提供隔离电源。该器件具有推挽式拓扑结构的简单性、低 EMI 和磁通消除等优点,可防止变压器饱和。采用占空比控制技术来减少宽输入范围的元件数量,同时选择高开关频率来缩小变压器尺寸,从而进一步节省空间。

该器件集成了控制器和两个异相切换的 0.5A NMOS 电源开关。其输入工作范围通过精密欠压锁定进行编程。该器件通过过流保护 (OCP)、可调节欠压锁定 (UVLO)、过压锁定 (OVLO)、热关断 (TSD) 和先断后通型电路来防止出现故障条件。

可编程软启动 (SS) 可尽可能减少浪涌电流,并为满足关键的上电要求提供电源时序。展频时钟 (SSC) 和引脚可配置的压摆率控制 (SRC) 进一步降低了辐射和传导发射,以满足超低 EMI 要求。

SN6507-Q1 可采用 10 引脚 HVSSOP DGQ 封装。该器件的运行温度范围为 –55°C 至 125°C。
