SC4510ITSTRT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

SC4510ITSTRT属于集成电路（IC）的PMIC-稳压器-DCDC开关式控制器。由Semtech Corporation制造生产的SC4510ITSTRTDC-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。

Description

The SC4510 can be configured as a synchronous buck convertor capable of sourcing and sinking current from load without losing output regulation. The output can be set to track an internal reference or an external voltage. The actual reference used by the error amplifier is buffered and brought out as a reference. It is the ideal choice for externally referenced or tracking buck convertors such as those for DDR memory applications.
