RT7739LA系列为强化高效能多重模式脉波宽度调变(PWM)之返驰式转换控制器， 并加入立锜的智慧型抖频技术 (SmartJitter<SUP>TM</SUP>) 之专利。创新的智慧型抖频技术，不仅可降低系统进入绿能模式所造成之电磁干扰，亦可消除输出抖频纹波。同时，RT7739LA兼具多重模式控制方案，可在连续导通模式 (CCM) 于具谷底切换至非连续导通模式 (DCM) 控制，达到产品效能升级之效益。</br>RT7739LA为用于返驰式转换器的电流模式脉波宽度调变控制器。RT7739LA更结合完整及可编程的安全保护机制，包含：传输延迟补偿、输出过电压保护、外部过温度保护、大电容Brown-in/Brown-out保护。让产品研发设计者得更灵活的设计应用对应的商品，以较少的零件数及较低的成本，开发设计高效节能AC-DC电源产品。本产品的封装为SOT-23-6。
