.. a short circuit or another high-current fault in one of several loops powered by a single source can produce a power-supply failure that disables all transmitters powered by that source. Intrinsically safe loops, on the other hand, ...
.. article describes a portable breadboard-friendly adjustable power supply, designed as an ideal supply for Arduino projects and other low-power circuits. It is capable of providing ...
.. normal battery discharge, “brownouts,” or simply connecting the wrong “brick” to the system. When supply voltage drops below a minimum threshold, it’s often good practice to disconnect the supply from the ...
.. analog switches and an accurate voltage reference to the usual PWM topology, thus isolating the DAC output from logic supply inaccuracy. One switch generates a precision version of the usual PWM waveform while the other generates its ...
.. can use simple circuits to implement small, regulated plug-in power supplies. In Figure 1, a basic and versatile 5 V supply uses a zener diode and an emitter-follower transistor. You must calculate and design the transformer such ...
.. ICs are commonly used in variable power supplies. Common types such as the 317 can be adjusted as low as 1.25 V in single-supply applications. At low output voltages power losses in these regulators can be a problem. For example, if an ...
.. output current. Hence, I IN approximately equals I L . Equation 1 expresses the dc output power that the inductive power supply produces: (1) This equation shows that the output current is constant and therefore the dc output power, P X ...
.. an intrinsic property of collector voltages in one-transformer pushpull dc/dc converters: They have a swing of twice the supply voltage. When you implement these circuits with an NPN device, the collector swings from 0 V to twice the ...
.. “new fangled” circuit designs. Figure 1 shows a useful example. Figure 1. Symmetrical-output variable power supply uses single DC source with classic 3-leg regulators, one regulator (U3) operates in shunt mode as ...
The traditional analog function generator with its customary triple-threat ensemble of square, triangle, and sine waveform outputs is a familiar tool on electronics lab benches. It’s also a classical design exercise. Generally, the square and ...
