LM386 Amplifier Circuit [Working and Application Circuits]
The IC LM386 is a 8-pin tiny power amplifier chip, specially made for operating under relatively low voltage parameters, yet provide considerable amplification. IC LM386 amplifier circuit becomes suitable for applying in small low power audio gadgets like in FM radios, door bells, telephones etc. Let’s begin the IC LM386 amplifier explanation by studying its absolute maximum ratings […]
How Buck-Boost Circuits Work
We all have heard a lot about buck and boost circuits and know that basically these circuits are used in SMPS designs for stepping up or stepping down a given voltage at the input. The interesting thing about this technology is that it allows the above functions with negligible heat generation which results in a […]
Inductors in AC/DC Circuits Explained
In this post I have explained the response of inductors to DC and AC voltages as well as when applied with capacitors which is often used as a complementing part with an inductor. Properties of Inductor Inductors are known for their property of storing electrical energy in them in the form of magnetic energy. This […]
How Switch Mode Power Supply (SMPS) Circuits Work
SMPS is the acronym of the word Switch Mode Power Supply. The name clearly suggests that the concept has something or entirely to do with pulses or switching of the employed devices. I have explained how SMPS adapters work for converting mains voltage to a lower DC voltage. Advantage of SMPS Topology In SMPS adapters […]
Simple Water Level Indicator Circuits (with Images)
A water level indicator is an electronic circuit which indicates the various levels of water inside a tank. This happens when rising or dropping water levels come in contact with the respective water sensors arranged step wise inside the water tank at different depths. In this post I have explained 2 interesting ways to make […]
