.. switch (ATS). An ATS is a clever piece of hardware that automatically shifts the electrical load from your primary power supply to a backup or standby source like a generator when it detects an outage. The result? A stable, uninterrupted ...
.. necessary. The circuit shown generates a low frequency square wave signal while drawing only 0.5 microamps from a 6 volt supply. The circuit uses a number of N and P channel MOSFETs, contained within an inexpensive CD4007UB IC. The ...
.. stolen from Q3’s phase control signal. This (as you probably noticed), nicely avoids the need for a separate power supply, but it provides only microamps of current for U1 and friends. So, a power-thrifty topology was definitely ...
.. SEPIC (single-ended primary-inductance-converter) topology, the converter operates from a 12 V battery-backed input supply and outputs 24 V at 200 mA. The key feature is the second “coil,” which is not a coil but rather ...
.. excessively high voltages. Q 3 , Q 4 , Q 5 , and associated circuitry allow for blocking the converter when the power supply to the circuit is too low. A too-low power-supply level may lead to an output-pulse amplitude from IC 2 that ...
.. condenser microphones require a 48-V supply to charge the internal capacitive transducer and power the internal buffer for the high-impedance transducer ...
.. need current to illuminate, and current usually flows through a power supply to an LED. A typical LED-driver circuit uses a transistor to provide current and a series resistor to ...
.. 1) has a high impedance input stage, it can operate reliably beyond 100 MHz, it can be operated with a single 5.25-V supply (or a single 5-V supply with a few added components), and it has been successfully simulated. Also, ...
.. high voltage feature, Jayapal’s design switches the negative (V SS a.k.a. “ground”) rail of the incoming supply instead of the (more conventional) positive (V DD ) rail. Of course, there’s absolutely nothing ...
.. published by Stephen Woodward. These are all designed for DC voltages less than 15 V, since this is the maximum power supply voltage of the CMOS ICs that were used in their design. There are several applications that use 48 VDC as the ...
