电源技术 高电压降压转换器驱动高功率LED
Introduction
电源技术 DN428微型同步升压转换器
 
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 ...
电源技术 DN465 超低功耗升压转换器
 
Industrial remote monitoring systems and keep-alivecircuits spend most of their time in standby mode. Manyof these systems also depend on battery power, so powersupply effi ciency in standby state is very important tomaximize battery life. The LT®8410/-1 high effi ciencyboost converte ...
电源技术 DN458降压转换器简化低电压设计
 
Many system designers need an easy way to producea negative 3.3V power supply. In systems that alreadyhave a transformer, one option is to swap out the existingtransformer with one that has an additional secondarywinding. The problem with this solution is that manysystems now use transfor ...
电源技术 超低功率转换器的控制方案消除开关噪声
 
An essential component of a noise-free audio device isa clean power supply, but few switching regulators canoperate at high efficiency while keeping the switchingfrequency out of the audio band. The LTC®3620 fills thisvoid. It is a high efficiency 15mA buck regulator with aprogrammabl ...
电源技术 数字电压表设计
 
数字电压表是大学物理教学和实验中的重要仪表，其数字化是指将连续的模拟电压量转换成不连续、离散的数字量并加以显示。传统的实验用模拟电压表功能单一、精度低、体积大，且存在读数时的视差，长时间连续使用易引起视觉疲劳，使用中存在诸多不便。而目前数字万用表的内部核心多是模/数转换器，其精度很大程 ...
电源技术 高效率,高密度,高电流应用的多相转换器
 
As logic systems get larger and more complex, theirsupply current requirements continue to rise. Systemsrequiring 100A are fairly common. A high current powersupply to meet such requirements usually requires parallelingseveral power regulators to alleviate the thermalstress on the individ ...
电源技术 高电压,低噪音,DCDC转换器
 
Photomultipliers (PMT), avalanche photodiodes (APD),ultrasonic transducers, capacitance microphones, radiationdetectors and similar devices require high voltage,low current bias. Additionally, the high voltage must bepristinely free of noise; well under a millivolt is a commonrequirement ...
电源技术 LT1300和LT1301在功率DCDC转换器中的应用
 
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 ...
电源技术 超低耗AC-DC电源转换器
电源待机能耗规范术语解释：
静态待机模式是指产品被关闭不执行任何常规功能但仍然与电源连接的空载状态,此时仅为低功耗微控制器和唤醒电路供电。比如有唤醒功能的电脑等电子产品，该微功耗电源在静态待机状态下功耗小于6mW，比能源之星静态待机功耗2.0和EuP标(300mW)还要低50倍，这么低的静态待机功耗世界无与伦比。
