.. heatsink! Also note that R S should be rated for a wattage of at least 1.252/R S . Then there’s the consideration of power up/down transients. When the system is first switched on and C 1 is sitting discharged, and the controller will ...
.. infrared (IR) signals while conserving system power is difficult, and typically requires the inclusion of complex power-management routines in the firmware. You ...
.. circuit of Figure 1 is designed for portable-power applications that require white LEDs with adjustable, logarithmic dimming levels. The circuit drives as many as ...
.. comparator compared to an IC comparator, which was used with an ultrasound application. To set up the test, a special power-supply circuit was designed for the comparator as well as for a crystal-clock module with specified jitter. The ...
.. been a lot of interesting conversation and DI teamwork lately devising circuits for ON/OFF power control using inexpensive momentary-contact switches (See Ref. 1 Ref. 4 ). Most of these designs have ...
.. and resistors while providing the maximum number of steps. An array or bank of load resistors is often required for testing power products, characterization of solar panels, and many other applications that require evaluation under various ...
.. turned on. Performance is far better than a FET, and unlike analogue switch ICs, you don't need to mess around with odd power supply voltages. In the off state, distortion is typically less than 0.004% and attenuation in the on state is ...
.. The cycle repeats at a frequency related to time constants within the bias network. Poor circuit layout or inadequate power-supply decoupling can also cause squegging. These causes are readily addressed, but the solution to the ...
.. rating isn’t much of an issue. A cool feature of this simple topology is that, unlike many other schemes for digital power supply control, only the regulator’s internal voltage reference matters to regulation accuracy. Precision ...
.. time proven Bob Pease masterpiece! However, unlike the earlier design idea that requires a floating, fixed output 24-VDC power adapter, this sequel incorporates a ground-referred boost preregulator that can run from a 5-V regulated or ...
