There are several ways on how to sweep current in LTSpice. You can do it through DC sweep command tab, using the step command or through the list command in the spice directive. For first timer in LTSpice, click this beginner’s tutorial. In this tutorial I assume that you have already basic knowledge on LTSpice so I jump directly to

In this article we are going to explore the ways on how to sweep voltage in LTSpice. Personally I like LTSpice, aside from being a freeware, it is easy to use. It really does what paid simulation software can do (although not that fast when dealing with analog simulation such as switching power supply). For beginners guide, click />this. There

One of the easiest methods to tune a controller is through automatic tuning. This is the principle of control tuning using Simulink auto tune feature. Unlike root locus tuning in Matlab, control tuning using Simulink auto tune feature is very easy to do and can be done in a short duration only. However, you still need to know the plant

This design reference is for 7V to 25V input with 5V and 1.5A output buck converter using LT1376-5 controller. LT1376-5 is monolithic buck mode switching regulator which has a fixed frequency of 500 kHz. The switching element is internal on the controller thus lower component count. The internal switch can able to handle 1.5A current. The controller can be used with

Is it worth investing for power supply with low standby power? Come; go with me to explore the answer of this question. Nowadays power supply technology is advancing. There are so many features added that may or may not be useful for end users. It is important for the end users to define his requirements so that to get the

There are few methods to do control tuning in Matlab. One of these is control tuning using root locus editor in Matlab SISO feature. Unlike control tuning using Simulink which is automated, control tuning using root locus editor in Matlab is a manual tuning. On below figure, the upper left box is the root locus editor where you tune your

Will my electric bill decrease when I unplug appliances not in use? This is the question of many people perhaps. Let us find out if there is really a savings from unplugging devices not in use. Many of us rely only in the remote control to put our appliances in sleep mode or standby mode but not totally cutting the power

Below are the guides on how to know if MOSFET is defective. These are the most common techniques that can be used to check if MOSFET is defective. Step #1 How to Know if MOSFET is Defective – Diode Check The first thing we will try on how to know if MOSFET is defective is to check the diode drop.
READIn electronics industry, protecting devices from ESD damage is a must. Electrostatic discharge or simply ESD is a very high voltage spike that can easily damage small signal components such as integrated circuits and low power semiconductors. A common ESD is caused by human body touching to electronic devices. Charges are accumulating inside human body and then when any part

High side driver design using PMOS is an easy approach on driving a high side load. High side driver is the term used because once the switch turns on, it will connect the load to the circuit supply to complete the current path. A load is not limited to resistors, it can also an inductive such as relay and lamp.
