单开关(或称单晶体管)正激转换器是一种最基本类型的基于变压器的隔离降压转换器，广泛用于需要大降压比的应用。这种转换器的优点包括只需单颗接地参考晶体管，及非脉冲输出电流减小输出电容的均方根纹波电流含量等。但这种转换器的功率能力小于半桥或全桥拓扑结构，且变压器需要磁芯复位，使这种转换器的最大占空比限制在约 ...

DC-DC 模块的电源纹波指标是一项很重要的参数。干净的电源是数字电路稳定工作的前提，也是模拟器件的各项参数的重要保障。

进入90年代以来，各种单片真有效值／直巍(TRMS／PC)转换器正在国内外迅速推广应用，构成具有高性价比的各种真有效值仪表。本文重点介绍AD6 37的工作原理与典型应用。

  Easy-to-use and compact point-of-load power suppliesare necessary in systems with widely distributed, highcurrent, low voltage loads. The LTC®3415 provides acompact, simple and versatile solution. It includes a pairof integrated complementary power MOSFETs (32mΩtop and 25m&Omega ...

  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 re ...

  Speed and accuracy don’t always go hand-in-handin DC/DC converter systems—that is, until now. TheLTC3811 is a dual output, fi xed frequency current modeDC/DC switching regulator controller designed for one oftoday’s most demanding power supply applications: highcurrent, ...

  Alkaline batteries are convenient because they’re easy tofi nd and relatively inexpensive, making them the powersource of choice for portable instruments and devicesused for outdoor recreation. Their long shelf life alsomakes them an excellent choice for emergency equipmentthat may ...

  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. Thi ...

  The design of battery-powered equipment can often bequite challenging. Since few ICs can operate directly fromthe end-of-life voltage from a 2-cell battery (about 1.8V),most systems require a DC/DCconverter. The systemdesigner often has a limited area in which to place the DC/DC converter ...
