Журнал РАДИОЛОЦМАН, апрель 2013 Tai-Shan Liao, Тайвань EDN При чрезмерной мощности излучения даже кратковременное попадание в глаза луча лазерной указки может быть опасным для здоровья человека, как при прямом воздействии, так и при отражении от ...
Tai-Shan Liao, National Applied Research Laboratories, Instrument Technology Research Center, Hsinchu, Taiwan EDN An excessive level of light from a laser pointer, even if only for a short duration, can be harmful if it enters the human eye either ...
Application Note AN142 November 2013 Christian Kueck Switching regulators replace linear regulators in areas where low heat dissipation and efficiency are valued. The switching regulator is typically the first active component on the input power ...
Application Note AND9100/D September 2012 High power systems require the paralleling of IGBTs to handle loads well into the 10's and sometimes the 100's of kilowatts. Paralleled devices can be discrete packaged devices, or bare die assembled within ...
Application Note AN4339 November 2013 Harjeet Singh Due to recent directives by the Bureau of Energy Efficiency (BEE) to reduce power consumption of consumer loads, it is necessary to analyze energy consumption by each of the house hold loads and ...
Application Note AN4277 November 2013 The purpose of this document is to describe STM32F30x/31x timer break feature and show how it can be used with other STM32F3 internal resources for over-current and over-voltage protection in applications such ...
Application Note AN-4155 March 2013 Fairchild recently developed a field-stop, shorted-anode, insulated-gate, bipolar transistor (IGBT) product family; ranging from 1100-1400 V and including an intrinsic body diode. Since the intrinsic ...
Виртуальная земля необходима, когда требуется организовать двуполярное питание, располагая лишь однополярным источником, например, батареей в портативном устройстве. Иногда сделать это совсем несложно, создав среднюю точку с помощью делителя из ...
A virtual ground is useful whenever you need to create a bipolar supply but the dc source is unipolar, as is often the case with battery-operated equipment. Sometimes, the solution is as easy as using a high-ohm resistive divider to provide a ...
Application Report SLUA632 March 2012 Umar Lyles, Yogesh Ramadass Battery Charge Management System and Design The bq25504 is an ultra-low-power charger IC intended for interfacing DC sources like solar cells, thermal harvesters and high-impedance ...
Application Report SLUA691 July 2013 Jeff Falin This application note explains how the data for the bq25504 data sheet efficiency curves was measured. Efficiency for output voltage regulating power supplies (that is, ac/dc or dc/dc converters) is ...
Application Report SLUA629A January 2012 Karthik Kadirvel and John Carpenter Battery Charge Management Ambient light sensors have become very common in portable electronics to adjust the brightness of the screen. These sensors automatically ...
