数据： TPS40200 Wide Input Range Non-Synchronous Voltage Mode Controller 数据表
TPS40200是一款灵活的非同步控制器，内置200-mA驱动器，用于P沟道FET。该电路的输入电压最高可达52 V，具有省电功能，可在外部FET完全导通后关闭驱动器电流。此功能扩展了器件的灵活性，允许其在高达52 V的输入电压下工作，而不会消耗过多的功率。该电路采用电压模式反馈工作，具有前馈输入电压补偿，可立即响应输入电压变化。整体700 mV基准电压调整为2％，提供精确控制低电压的方法。 TPS40200采用8引脚SOIC和8引脚VSON封装，支持更复杂控制器的许多功能。时钟频率，软启动和过流限制均可通过单个外部组件轻松编程。该器件具有欠压锁定功能，可轻松与其他控制器或系统时钟同步，以满足排序和/或降噪要求。
