RT7740是改善了效率表現的多模態反激式開關電源PWM控制器，其中使用了立錡專有的智慧抖頻（SmartJitter<SUP>TM</SUP>）技術，具有節能模式EMI輻射水準低的特性，同時消除了頻率抖動對輸出紋波的影響。它具有多種控制模式，可工作在連續導通模式、非連續導通模式和穀底切換的非連續導通模式，效率高，性能好。<Br>RT7740將電流模式PWM控制技術應用於反激式轉換器中，同時還具有各種可調保護特性如延遲補償機制、輸出過壓保護、週邊過熱保護、大電容Brown-in/Brown-out保護等，可被使用於要求性價比高、體積緊湊、電壓範圍寬的AC/DC應用中，其封裝形式為SOT-23-6。<br>建議的接面溫度範圍為-40°C至125°C，而環境溫度範圍則為-40°C至85°C。
