發現并證明了在設計多路大電流DC-DC變換器時,如果對每個工作模塊進行有效隔離可避免自激情況發生。這個發現可更好地指導設計大電流多路DC-DC變換器。

便攜式電子器件(如智能手機、GPS導航系統和平板電腦)的電源可以來自低壓太陽能電池板、電池或AC/DC電源。電池供電系統通常將電池串聯疊置以實現更高的電壓，但由于空間不足，此技術未必總是可行。開關轉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，所以開關轉換器是個不錯的高效率選擇。連接至轉換器輸出端的電容可減少輸出電壓紋波。升壓轉換器提供較高的輸出電壓；而應用筆記AN-1125(如何運用DC-DC降壓調節器)所討論的降壓轉換器則提供較低的輸出電壓。內置FET作為開關的開關轉換器稱為開關調節器，需要外部FET的開關轉換器則稱為開關控制器。

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.

The LTM4601 DC/DC μModule regulator is a completehigh power density stepdown regulator for up to 12Acontinuous (14A peak) loads. The device is housed ina small 15mm ¥ 15mm ¥ 2.8mm LGA surface mountpackage, thus the large power dissipation is a challengein some applications. This thermal application note willprovide guidelines for using the μModule regulator inambient environments with or without air fl ow. Loadcurrent derating curves are provided for several inputvoltages and output voltages versus ambient temperatureand air fl ow.
