AX3010/3011系列为一颗脉波宽度调变输出的异步流降压转换器，输入电压最高可到45伏特，输出电压可以依需要调整最低1.155伏特到最高38伏特，非常适合于汽车用电子系统，车用充电装置等车载系统的电压转换。

      AX3010/3011应用上可提供高转换效能(可达90%)及稳定的工作电压，输出电压的瞬时响应快，而输出电容适用于电解电容或陶瓷电容，其内部具有完整的系统保护功能包括暖开机, 短路保护(SCP) 、过温度保护(OTP)及过电流保护(OCP)功能，并整合了两种型式(内部或外部关断功能)的过电压保护机制(OVP)以避免过电压时对电路烧毁之风险, 而在短路保护时会将原先频率降低(AX3010/3011降为10KHz, AX3010A/3011A降为20KHz),降低短路时IC所消耗能量,避免IC过热。

      AX3010/3011采用标准含散热片之SOP-8LEP无铅封装与极少的外部组件可大幅缩小印刷电路板的面积，具有散热片可以将热导至印刷电路板上，大幅降低组件表面温度以符合客户需求。
