Transistor Operation Mode Determination

Transistor operation mode is can easily be determined by using mathematical equations. Don’t worry; these are not difficult equations. There

For power devices like power MOSFETs, power BJT and power diodes, heat sink is very important to provide thermal relief.

MOSFET RDSon temperature coefficient is positive. Meaning, it will increase with increasing temperature. In this article I will discuss and

In this article I will discuss the proper way on how to use MOSFET RDSon data provided by datasheets. RDSon

I believe there are few ways to perform worst case analysis and tolerance simulation using LTSpice. In this article, I

In this article I will discuss the feature of the NPN transistor biasing tool and checker in excel that I

One of the most important parts of a buck converter is the inductor. Sizing the inductor of buck converter and

In this article I will share to you the methods I used in buck converter duty cycle derivation. We will

The most common application of Optocoupler is signal isolation. It provides complete isolation because its input side is not electrically

In optocoupler, CTR stands for current transfer ratio. This is comparable to the current gain beta in BJT. This is
