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.

什么是DC/DC 轉換器? 什么是DC(Direct Current)呢?它表示的是直流電源，諸如干電池或車載電池之類。家庭用的100V電源是交流電源(AC) 。若通過一個轉換器能將一個直流電壓(3.0V)轉換成其他的直流電壓(1.5V或5.0V)，這個轉換器被稱為DC/DC轉換器或稱之為開關電源或開關調整器。 DC/DC轉換器一般由控制芯片，電感線圈，二極管，三極管，電容器構成。 DC/DC轉換器為轉變輸入電壓后有效輸出固定電壓的電壓轉換器。DC/DC轉換器分為三類：升壓型DC/DC轉換器、降壓型DC/DC轉換器以及升降壓型DC/DC轉換器。根據需求可采用三類控制。PWM控制型效率高并具有良好的輸出電壓紋波和噪聲。PFM控制型即使長時間使用，尤其小負載時具有耗電小的優點。PWM/PFM轉換型小負載時實行PFM控制，且在重負載時自動轉換到PWM控制。目前DC-DC轉換器廣泛應用于手機、MP3、數碼相機、便攜式媒體播放器等產品中。

When a system designer specifies a nonisolated DC/DC powermodule, considering the needed input voltage range isequally as important as considering the required performanceattributes and features. Generally, nonisolated moduleshave either a narrow or a wide input voltage range. Narrowinputmodules typically have a nominal input voltage of3.3, 5, or 12 V. For systems that operate from a tightlyregulated input bus—such as those that do not use batterybackup—a narrow-input module is often adequate sincethe input remains fairly stable.Offering greater flexibility, wide-input modules operatewithin a range of 7 to 36 V, which includes the popular12- or 24-V industrial bus. This enables a single module tobe used for generating multiple voltages. These modulesare ideal for industrial controls, HVAC systems, vehicles,medical instrumentation, and other applications that usea loosely regulated distribution bus. In addition, systemspowered by a rectifier/battery charger with lead-acidbattery backup almost always require wide-input modules.System designers who choose power supplies may wantto take a close look at the latest generation of wide-inputDC/DC modules.
