RT5785A/B是高性能、先进的恒定导通时间（ACOT™）单芯片同步降压型DC/ DC转换器，可从2.5V~6V的输入电源提供高达2A的输出电流。专有的ACOT控制架构具有快速瞬态响应，并以小陶瓷输出电容器及没有复杂的外部补偿来提供稳定的操作。开关涟波电压能容易地平稳通过小型封装过滤组件，由1.5MHz和100％最大占空比的恒定开关频率允许设备在低压差操作使用。随着内部低导通电阻功率开关和极低的静态电流，RT5785A/B在一系列的应用程序中显示优异的效率和良好的表现。</br>逐周期电流限制提供保护机制对抗短路输出，输入欠压锁定、输出欠压保护及过热关机保护提供所有运行条件下安全、平稳运行。RT5785A/B采用TSOT-23-8（FC）封装。
