SC4510ITSTR集成電路（IC）的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器規(guī)格書PDF中文資料

SC4510ITSTR屬于集成電路（IC）的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器。由Semtech Corporation制造生產(chǎn)的SC4510ITSTRDC-DC 開關(guān)控制器PMIC（電源管理集成電路）DC 到 DC 開關(guān)式控制器是用于高效率電路的穩(wěn)壓 IC，其配置為生成高于（突升或步升）或低于（突降或步降）輸入電源的輸出電源電壓。其他拓撲結(jié)構(gòu)可能包括：降壓-升壓、反激、正激、Cuk、SEPIC、全橋、半橋和推挽式。這些器件不同于需要最小電壓并“燒盡”多余電壓的線性穩(wěn)壓器。

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.

Features
