- Philip KarantzalisIntroduction A common problem in power distribution systems is loss of regulation due to the cable/wire voltage drop between the regulator and the load. Any increase in wire resistance, cable length or load current increases the voltage drop over ...Oct 20, 2015
- Vladimir Rentyuk EDN Most engineers know that they can use an inexpensive, three-terminal adjustable regulator, such as Fairchild Semiconductor’s LM317 , as an adjustable regulator to only some necessary value of voltage, such as 36 or 3 V. ...Oct 13, 2015
- Sajjad HaidarWhen a MOSFET or IGBT gate-threshold voltage is higher than the available drive voltage, it's standard to use an op amp or other driver to bridge the difference. This circuit uses a basic optocoupler plus a few simple passive components to ...Sep 30, 2015
- Vladimir Rentyuk EDN A TL431 shunt regulator is a perfect choice for many applications. You can use it as a comparator with hysteresis by taking advantage of its inner voltage reference along with few additional components. You can use this ...Sep 17, 2015
- Todor ArsenovMost isolated, offline SMPSs (switched-mode power supplies), including flyback, forward, and resonant, must operate at input voltages of 90 to 260 V rms. Some cases even use line-to-line voltages of 400 V rms 10%, leading to increased ...Sep 1, 2015
- Anthony SmithRequiring only a handful of inexpensive components, the circuit breaker in Figure 1 responds to both overcurrent- and overvoltage-fault conditions. At the heart of the circuit, D 2 , an adjustable, precision, shunt-voltage regulator, provides a ...Aug 20, 2015
- Keith Szolusha Tage BjorklundDesign Note 521 Introduction A DC/DC converter’s efficiency and component temperature are important considerations in high power applications where high current could overheat the catch diode used in an asynchronous buck or boost topology. ...Aug 19, 2015
- Charlie Zhao, Linear Technology Design Note 532 Introduction The wide 4 V to 150 V input range of the LTC3639 stepdown DC/DC converter allows automotive, avionics and distributed power systems to: Cover extensive transient requirements Enable ...Jul 30, 2015
- Sajjad HaidarPower supplies with adjustable DC output ranging from 0 V to 30 V or 60 V are on the market. Above 60 V, there are not many. This Design Idea offers a solution. There are many fixed voltage switching mode power supplies (SMPS) available, and ...Jul 15, 2015
- Mitchell LeeAs the power consumption of individual cards increases in rack-mounted systems, current consumption necessarily follows suit. A point is reached where the current delivered by the backplane becomes untenable, and the only solution is to increase ...Jul 15, 2015
