RT8296A General Description ：3A,23V,340kHz同步降壓DC-DC
RT8296A是一種高效率，單片同步降壓式DC / DC轉換器從4.5V至23V輸入電源，可提供高達3A的輸出電流。RT8296A的電流模式架構和外部補償允許瞬態響應，要通過廣泛的負載和輸出電容進行了優化。RT8296A逐周期電流限制提供了針對輸出短路保護，軟啟動消除了啟動期間的輸入浪涌電流。故障條件還包括輸出欠壓保護和熱關機。RT8296A低電流（<3μA）關斷模式下提供輸出斷開，使容易的電源管理電池供電系統。RT8296A是可以在一個SOP - 8（裸露焊盤）封裝。
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.
