TPS40055-EP

illustrate

该TPS40055是一种高电压，宽输入家庭（8 V至40 V），同步，降压转换器。 该TPS40055系列提供了用户可编程的各种功能，包括软启动，欠压锁定，工作频率，电压前馈，高边电流限制及环路补偿设计的灵活性。

该TPS40055也可同步至外部电源。 该TPS40055集成了外部N通道高侧和同步整流器（SR）的MOSFET的MOSFET的栅极驱动器。 Drive logic gate reversal circuitry is used to prevent cross-conduction synchronous high-side and synchronous rectifier conduction.

该TPS40055采用电压前馈控制技术，提供了广阔的（4:1）输入电压范围内具有良好线性调整率和快速响应与输入的变化接近从而简化环路补偿恒定增益，输入电压瞬态。
