SC453TSTRT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

SC453TSTRT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SC453TSTRTDC-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 SC453 IC is a single chip high-performance Hysteretic PWM controller. With its integrated SmartDriver™, it pow ers advanced graphics and core processors. It provides sleep mode and boot voltage support. Automatic power save is present to prevent negative current flow in the

low-side FET during light loading conditions saving even more power. The high side driver initially turns on with a weak drive to reduce ringing, EMI, and capacitive turn-on of the low side.
