.. 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 ...
.. are multiple means of generating analog sawtooth waveforms. Here’s a method that employs a single supply voltage rail and is not finnicky about passive component values. Figure 1 shows a pair of circuits that use a ...
.. between output voltage and resistor mismatch. A possible drawback is the price: instrumentation amplifiers with a power supply of 5 V and more start at about 6.20 USD. Figure 3 shows another circuit using a dual op-amp, which is 2.6 ...
.. 1; For part values shown A cool feature of the Figure 1 topology is that, unlike some other schemes for digital power supply control, only the precision of R1, R2, and the regulator’s own internal voltage reference determines ...
