LTspice IV

If you are familiar with freeware switching regulator applications then you should know that it has become difficult lately to find a compatible and easy to use application for everyone's waveform viewing needs. This fourth installation of the LTspice deserves a shoutout with its easy to use, quick, and more streamlined UI. Right of the bat when you open the program you know you are in for a treat with how quick you are able to switch regulators. Compared to the competition it should be no contest on who the user should choose when it comes to switching regulator applications. Some of the key features in this installment makes it easy at least for me a novice in the field to choose and quickly use. Most experienced users in the field should also be happy with this new installment as it retains a lot of the previous features and some new ones as well. 

Features

• Includes macro modules for most of the analog devices and switching regulators
• More than 200 op amp models, resistors, transistors, and MOSFET models.
• Quick and easy to use UI 
• Able to enhance SPICE to make simulating switching regulators easy, fast, and more streamlined. 

In conclusion, this application has made my everyday waveform viewing tasks easier which is something that everyone should be interested in. I was almost going to give up on LTspice after their last installment, which I was not a big fan of, to be honest. But this newest and latest installment has been great for me so far and I couldn't be happier with the way I was able to just open up the program, and get to work. It has saved me many hours of extra work and unnecessary wait time in between viewing sessions. Big fan of this one, I am looking forward to using this program more, and most importantly any future installments from LTspice. 

It has made simulating switching regulators quicker in comparison to the competition, allowing the user to complete tasks where they have to view waveforms for most switching regulators faster.
