... Applications of the LDR Textbooks often mention that LDRs are used to switch on street lights when it gets dark, yet this can seem confusing because the resistance of the LDR is high when it is dark so how can this be responsible for current flowing through the street-light? What actually happens i ...

... The minimum on-time of the device is 1.6 µs. At light loads, this would cause a low switching frequency in the audible range because the energy transferred to the output during the on-time would cause a higher rise in the output voltage than needed and therefore lead to a long off−time until the out ...

... The UVP feature protects against open loop conditions in the feedback loop. If the FB pin is inadvertently floating (perhaps due to a bad solder joint), the coupling within the system may cause VFB to be within the regulation range (i.e. VUVP < VFB < VREF). The controller responds by delivering maxi ...

Valve RF amplifier
A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
