TOREX的XC9221系列是多功能降压DC/DC控制器IC。给该芯片外部配备一种开关器件，一种功率电感，一种二级管和两个电容就能获得一种高效率,相对稳定的，输出电流高至3A的开关电源。能使用低ESR电容例如陶瓷电容用作其输出电容。

XC9221系列控制器有个0.9V(±1.5%)基准电压，采用外置采样电阻就可以随意设定输出电压。工作频率为300kHz,500kHz和1MHz，

XC9221系列控制器能使用中小型外部器件。针对软启动时长，XC9221A和C系列是内部设置为4ms，XC9221B和D系列能够在外部设定。XC9221系列控制器具备内嵌的UVLO（欠压锁闭）功能性，当输入电压降至2.3V或更低情况下，外部的P端面开关器件将会被强制性关闭。

特征

工作电压范围：2.8V～16.0V

输出电压外部设定：0.9V(准确度±1.5V)

工作频段：300k,500k,1.0MHz

控制方法：PWM/PFM自动启动控制

带软启动特性：内部设定4ms(TypeA500kHz),外部设定(TypeB)

短路保护：积分保护1.0ms(A,B类型),短路保护

低ESR电容：陶瓷电容

TOREX半导体主要提供COMS、传感器、二极管等元器件，产品以小体积、性能卓越而著名。
