TC1055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

TC1055屬于集成電路（IC）的PMIC-穩(wěn)壓器-DCDC開關(guān)式控制器。由微芯科技股份有限公司制造生產(chǎn)的TC1055DC-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?fù)浣Y(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。

GENERAL DESCRIPTION

The TC1054 is a high accuracy (typically ±0.5) CMOS upgrade for older (bipolar) low dropout regulators. Designed specifically for battery-operated systems, the TC1054’s CMOS construction eliminates wasted ground current, significantly extending battery life. Total supply current is typically 50μA at full load (20 to 60 times lower than in bipolar regulators!).
