centered around switching power supplies with built-in step-down FET, and has devices suitable for a variety of supply current values, from small to large current. The Simple DC/DC series of power supply ICs has one to four channels of output and offers a simple and easy power design ...
ahappy day 愉快的天 [translate] aThe change from centralized power - a simple AC-DC power supply, perhaps with battery backup, feeding the cards in a system rack - came about by necessity. 从集中化力量的变动-简单的AC-DC电源,或许与备用电池,在系统机架哺养卡片-获得了必要。 [translate] ...
After testing proved that this design uses a 5V DC power supply, meet the basic features of MP3 player. Select VS1003 digital decoder chip, because of its simple operation, good sound, high integration, and the price is cheap. To play main stream bit rate of MP3 music files. MP3 Player...
You can further improve the above transformerless power supply design by replacing R2 and R3 with a single 5 ohm NTC thermistor. How to Calculate the above Circuit Assumptions: Let's assume we have the following parameters in hand: Output Voltage (Vout): 12V DC. ...
Improved Simple Adjustable DC Power Supply: Work in progress: I'll add more text explaining how this thing actually works and a schematic image in the next few days.There are already a few instructables about using linear voltage regulator chips to power
The faults occurred in three substations are due to uncertainty of DC power supply, resulting in malfunction of relay protection and extending the scope of cut-off of supply. So a necessary method should lie carried out to solve the problem. There is an another protective power supply, which ...
