Once a simulation is made, the confidence level that it will work in actual is very high. This will reduce development lead time and save parts cost for trial and error. Let me share you ACDC linear power supply simulation in LTSpice. For more tutorials, join electronicsconsultation.

This article features a low parts count ACDC 5 Watts Charger Design with an output voltage of 5V and a maximum charge current of 1A. This is applicable for cell phones, tablets and other devices and gadgets that use 5 volt supply. This is a constant voltage constant current charger. A constant voltage means a steady level of the output

Electrostatic discharge or simply ESD is a universal problem in electronic circuits. Capacitor as ESD protection is providing economical solution to the problem. I used to work in automotive electronics and we used high frequency capacitors to protect the exposed pins of our product. Exposed pins are the one accessible to users. There are several ways to protect devices from

Switching power supply operation is very different to that of linear power supply. Despite of its complexity, higher bill of material cost and higher parts count, switch mode power supply is still the preferred power supply topology in the market nowadays. The main reason is higher efficiency and higher power density. Higher efficiency simply means that only a small portion

With very convincing demos and promising very huge savings in the monthly bill are the most often point of sales of these advertisers. But let us uncover the reality of this electricity saving box scam. Electricity saving box or energy saving box or a.k.a power saver that plugged to the wall outlets (as simple as that) is a real scam.

Transistor operation mode is can easily be determined by using mathematical equations. Don’t worry; these are not difficult equations. There are three operation modes to operate the transistor. These are cut-off, saturation and linear. In cut-off, the transistor is simply not conducting; so it is not a problem to send the transistor in this region. You can simply do that

For power devices like power MOSFETs, power BJT and power diodes, heat sink is very important to provide thermal relief. From the name itself, it will sink the heat from the power devices and help controls the temperature in the safe zone. In this article I will discuss heat sink thermal resistance calculation. For a system with forced cooling method,

I believe there are few ways to perform worst case analysis and tolerance simulation using LTSpice. In this article, I will be sharing my own technique. This can be an easier approach and at the same time you will have your Monte Carlo analysis and simulations already. Basically, I will be making use of the Monte Carlo run to come

One of the most important parts of a buck converter is the inductor. Sizing the inductor of buck converter and setting its operation mode makes the converter function correctly. The shape and the magnitude of current of the inductor are dictated by the inductance of the inductor itself. Therefore choosing the right inductor value is very important. Sizing the inductor

In this article I will share to you the methods I used in buck converter duty cycle derivation. We will consider the ideal and the real scenarios. In ideal buck converter duty cycle derivation, you don’t need to consider the voltage drops of the switching element and catch diode. On the other hand, in real buck converter duty cycle derivation,
