.. is ostensibly a buck converter to provide a 5 V output. The optimum solution would be a bifilar wound coil with heavy gauge wire for the main 5 V output and smaller wire for the overwinding. To avoid a custom coil design, an off-the-shelf ...
Here is the circuit in Figure 1 from a previous DI ( Ref. 1 ): Figure 1. Simple local low-noise voltage converter that can be used when a simple negative supply of low voltage is required. It is simple, and its efficiency can be improved by a very ...

.. IC 1 ’s feedback input rests at 0.8 V, and IC 2 and R 2 form a voltage divider. The ADSP-BF531 imposes several design requirements: Its core power-supply voltage must maintain its accuracy to within 25 mV and offer an ...
.. log of the input signal. Positive input half-cycles cause it to clamp low at V F , which we ignore, as this is a half-wave design; for negative ones, it swings high by 2V F . Driving that 2V F through another diode into the capacitor ...
.. comparable to a 74HC04. Figure 5. A buffer may be necessary to provide a full voltage excursion RESET signal. Oscillator design equations are unchanged from the usual 555 datasheet math, except that the timing capacitance used should be ...
.. at and below zero volts, generating symmetrical output signals, and processing bipolar analog inputs, are all examples of design situations where a few milliamps of negative voltage rail can be a necessity. Figure 1 shows a simple ...
.. exponential waves are much use for generating sines, especially when their amplitudes depend on the supply. (My original design spec was for a PP3/6LR61 battery, giving about 9 V or 4.5 V when new, and a lot less when not.) A different ...
.. associated with the circuit in Figure 1. T 1 is a signal transformer that you can modify by wrapping two turns of 14-gauge wire around the bobbin to act as the primary winding. Materials on the topic Datasheet Texas Instruments LM311 ... .. Note that the signal ground with respect to earth ground is floating; you must not tie these grounds together. The design in Figure 1 has successfully controlled fans and high-amperage universal motors (100 mA to 11 A). One example ...
