  • 如何运用DC-DC升压调节器

      便携式电子器件(如智能手机、GPS导航系统和平板电脑)的电源可以来自低压太阳能电池板、电池或AC/DC电源。电池供电系统通常将电池串联叠置以实现更高的电压,但由于空间不足,此技术未必总是可行。开关转换器使用电感的磁场来交替地存储电能,并以不同电压释放至负载。因为损耗很低,所以开关转换器是个不错的高效率选择。连接至转换器输出端的电容可减少输出电压纹波。升压转换器提供较高的输出电压;而应用笔记AN-1125(如何运用DC-DC降压调节器)所讨论的降压转换器则提供较低的输出电压。内置FET作为开关的开关转换器称为开关调节器,需要外部FET的开关转换器则称为开关控制器。

  • DN385 10A高性能点的负载DC/DC微型模块

      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.

  • 降压升压型控制器简化手持式产品的DC/DC转换器设计

      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.

  • LTM4601 DC/DC微型模块性能

      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.
