RT8296A General Description ：3A,23V,340kHz同步降压DC-DC
RT8296A是一种高效率，单片同步降压式DC / DC转换器从4.5V至23V输入电源，可提供高达3A的输出电流。RT8296A的电流模式架构和外部补偿允许瞬态响应，要通过广泛的负载和输出电容进行了优化。RT8296A逐周期电流限制提供了针对输出短路保护，软启动消除了启动期间的输入浪涌电流。故障条件还包括输出欠压保护和热关机。RT8296A低电流（<3μA）关断模式下提供输出断开，使容易的电源管理电池供电系统。RT8296A是可以在一个SOP - 8（裸露焊盘）封装。
The RT8296A is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 3A output current from a 4.5V to 23V input supply. The RT8296A's current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. Cycle-by- cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start up. Fault conditions also include output under voltage protection and thermal shutdown. The low current (<3μA) shutdown mode provides output disconnect, enabling easy power management in battery powered systems. The RT8296A is available in a SOP-8 (Exposed Pad) package.
