S7133B系列芯片是一款高性能恒压恒流原边反馈控制器,适用于各种低功耗AC/DC充电器和适配器应用场合。该控制器采用原边反馈控制机制,无需光耦和TL431即可以实现高精度的电压输出。 在恒流控制模式中,可以通过改变与CS管脚连接的电阻Rcs阻值来调节输出电流大小。在恒压控制模式下S7133B使用了多种工作模式以得到高转换效率和小的音频异响。
Advantage
<75mW待机功耗,满足六级能效要求
准谐振工作机制,提高系统效率
峰值电流渐变抖动改善 EMI
内置功率三极管
恒压、恒流精度高
Application area
手机、无电话、PDA、MP3和其它便携式设备等的适配器、充电器
LED驱动电源
线性电压和RCC开关电源升级换代
PC、TV 等设备使用的辅助电源
