In “Evaluation of 50 Ω driver circuits for digital signals based on oscilloscope measurements” (Heliyon, Volume 7, Issue 7, July 2021) different 50 Ω driver circuits for digital signals were compared and evaluated. Notably, the BJT-based discrete push-pull driver circuit showed a rather mode...
BJT DRIVER WITH DYNAMIC ADJUSTMENT OF STORAGE TIME VERSUS INPUT LINE VOLTAGE VARIATIONSA controller for a power converter includes a driver circuit that generates a control signal to switch a power switch in response to an output, and a control circuit that controls the switching of the power ...
So while implementation details vary, the crux is that your microcontroller turns on an LED, and it’s the light from that LED that activates the other side of the circuit. The only connection between the LED side and the transistor side is non-electrical — light across a small gap — ...

For more information about the design of AC-DC constant voltage circuits, seePower Design. In the buck circuit based on the DC-DC converter IC, the area of the following primary power loops must be minimized: Loop 1: Signals run through the following components in sequence: the anode of C8...
burned in Q2. Thus for maximum efficiency, we want to configure our LED string so that it is close to the power supply voltage. It will work fine if we don't do this, we'll just waste power. this is really the only downside of this circuit compared to a step-down switching ...
Each point of time that the piezoelectric element, having properties comparable with a capacitor with capacitance C, is actuated by charging and discharging by a current source, an amount of power equal to ½ CV2 is dissipated in the driver circuit for each charging of the piezoelectric element...
