RT5758是可在3V至6.5V输入电压范围内输出高达9A电流的高性能同步Buck转换器，使用集成化的低R<SUB>DS(ON)</SUB>功率开关、0.6V参考电压和自举二极体，整体方案体积小巧，容易使用。</br>RT5758使用ACOT<SUP>TM</SUP>控制架构，具有超快的瞬态回应速度，周边元件数量极少。在稳定状态下，ACOT控制器工作在频率基本不变的状态下，与输入电压、负载大小和输出电压基本无关，EMI滤波器设计非常容易。</br>该器件提供独立的使能控制输入端子和Power Good指示信号，易于使用在需要时序控制的设计中。为了限制启动期间的输入电流冲击，晶片提供了可用外部电容调节的软起动端SS。晶片还集成有逐周期电流限制保护、欠压保护、输入欠压锁定保护和过热保护功能。</br>RT5758的封装形式为UQFN-13L 3x3 (FC)。
