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 转换器? 什么是DC(Direct Current)呢?它表示的是直流电源,诸如干电池或车载电池之类。家庭用的100V电源是交流电源(AC) 。若通过一个转换器能将一个直流电压(3.0V)转换成其他的直流电压(1.5V或5.0V),这个转换器被称为DC/DC转换器或称之为开关电源或开关调整器。 DC/DC转换器一般由控制芯片,电感线圈,二极管,三极管,电容器构成。 DC/DC转换器为转变输入电压后有效输出固定电压的电压转换器。DC/DC转换器分为三类:升压型DC/DC转换器、降压型DC/DC转换器以及升降压型DC/DC转换器。根据需求可采用三类控制。PWM控制型效率高并具有良好的输出电压纹波和噪声。PFM控制型即使长时间使用,尤其小负载时具有耗电小的优点。PWM/PFM转换型小负载时实行PFM控制,且在重负载时自动转换到PWM控制。目前DC-DC转换器广泛应用于手机、MP3、数码相机、便携式媒体播放器等产品中。

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.
