DC-DC 模塊的電源紋波指標是一項很重要的參數(shù)。干凈的電源是數(shù)字電路穩(wěn)定工作的前提，也是模擬器件的各項參數(shù)的重要保障。

便攜式電子器件(如智能手機、GPS導航系統(tǒng)和平板電腦)的電源可以來自低壓太陽能電池板、電池或AC/DC電源。電池供電系統(tǒng)通常將電池串聯(lián)疊置以實現(xiàn)更高的電壓，但由于空間不足，此技術(shù)未必總是可行。開關(guān)轉(zhuǎn)換器使用電感的磁場來交替地存儲電能，并以不同電壓釋放至負載。因為損耗很低，所以開關(guān)轉(zhuǎn)換器是個不錯的高效率選擇。連接至轉(zhuǎn)換器輸出端的電容可減少輸出電壓紋波。升壓轉(zhuǎn)換器提供較高的輸出電壓；而應(yīng)用筆記AN-1125(如何運用DC-DC降壓調(diào)節(jié)器)所討論的降壓轉(zhuǎn)換器則提供較低的輸出電壓。內(nèi)置FET作為開關(guān)的開關(guān)轉(zhuǎn)換器稱為開關(guān)調(diào)節(jié)器，需要外部FET的開關(guān)轉(zhuǎn)換器則稱為開關(guān)控制器。

Advancements in board assembly, PCB layout anddigital IC integration have produced a new generationof densely populated, high performance systems. Theboard-mounted point-of-load (POL) DC/DC power suppliesin these systems are subject to the same demandingsize, high power and performance requirements asother subsystems. The rigorous new POL demands aredifficult to meet with traditional controller or regulatorICs, or power modules.

A number of conventional solutions have been available forthe design of a DC/DC converter where the output voltageis within the input voltage range—a common scenarioin Li-Ion battery-powered applications—but none werevery attractive until now. Conventional topologies, suchas SEPIC or boost followed by buck, have numerousdisadvantages, including low effi ciency, complex magnetics,polarity inversion and/or circuit complexity/cost. TheLTC®3785 buck-boost controller yields a simple, effi cient,low parts-count, single-converter solution that is easyto implement, thus avoiding the drawbacks associatedwith traditional solutions.
