CS2841B集成电路（IC）的PMIC-稳压器-DCDC开关式控制器规格书PDF中文资料

CS2841B属于集成电路（IC）的PMIC-稳压器-DCDC开关式控制器。由安森美半导体制造生产的CS2841BDC-DC 开关控制器PMIC（电源管理集成电路）DC 到 DC 开关式控制器是用于高效率电路的稳压 IC，其配置为生成高于（突升或步升）或低于（突降或步降）输入电源的输出电源电压。其他拓扑结构可能包括：降压-升压、反激、正激、Cuk、SEPIC、全桥、半桥和推挽式。这些器件不同于需要最小电压并“烧尽”多余电压的线性稳压器。

The CS2841B provides all the necessary features to implement off−line fixed frequency current−mode control with a minimum number of external components.
