.. 1. Smart Power Supply for Microcontroller Projects. Note that the buck-boost conversion of TPS63000 is based on a fixed frequency, pulse width modulation controller using synchronous rectification to obtain maximum efficiency. ...
.. the overall design, a DC solid-state relay. Component values will depend on the required output current and the switching frequency. To minimize losses, diodes could be Schottky. Materials on the topic Datasheet Texas Instruments NE556
.. speaker, yielding the THD+N (total-harmonic-distortion-plus noise) curves (figures 2 and 3). Note that THD+N increases as frequency increases in both graphs. Because the speaker appears to the amplifier as a capacitor, the ...
.. voltages, you should add resistors R 2 and R 3 . These resistors add some hysteresis to the circuit, reducing the switching frequency. Typical values are 2.2 Ω and 2.2 kΩ, respectively. With the circuit in Figure 1, you can ...
.. heat the pulses deposit in Q 1 is where I is the amplitude of the Q 1 current pulses (adjusted with R 2 ), F is the output frequency, and W is the pulse width. W is inversely proportional to I D , the discharge current that ramps down V ...
.. low-power operation. The problem arises when you simultaneously require ultralow power consumption and relatively high-frequency operation. This scenario makes phenomenal demands on the micropower op amp. Consider that, every time ...
.. Williams EDN The VFC (voltage-to-frequency-converter) circuit in Figure 1 achieves a wider dynamic range and a higher full-scale output frequency ...
.. signals are similar to xDSL (digitalsubscriber- line) signals in that they both typically employ a form of OFDM (orthogonal frequency-division multiplexing). Both applications require high output current, wide bandwidth, and good ...
.. they use have switches to two or more windings and possibly a capacitor to reduce the drive current. But unless the drive frequency is also reduced, the torque and speed stability are poor, so minimal speed reduction is usually ...
.. Colman EDN In many applications, the frequency-conversion steps comprise a buffer, preferably with some extra voltage gain; a mixer; and some ...
