SC1102CSTR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

SC1102CSTR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SC1102CSTRDC-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。

Description

The SC1102 and SC1102A are low-cost, full featured, synchronous voltage-mode controllers designed for use in single ended power supply applications where efficiency is of primary concern. Synchronous operation allows for the elimination of heat sinks in many applications. The SC1102s are ideal for implementing DC/DC converters needed to power advanced microprocessors in low cost systems, or in distributed power applications where efficiency is important. Internal level-shift, high-side drive circuitry, and preset shoot-thru control, allows the use of inexpensive N-channel power switches.
