L6712AD集成電路（IC）的PMIC-穩(wěn)壓器-DCDC開關式控制器規(guī)格書PDF中文資料

L6712AD屬于集成電路（IC）的PMIC-穩(wěn)壓器-DCDC開關式控制器。由意法半導體集團制造生產(chǎn)的L6712ADDC-DC 開關控制器PMIC（電源管理集成電路）DC 到 DC 開關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。其他拓撲結構可能包括：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。
