New Product – The VRM

1

We here at Digilent are enthusiastic about announcing a new Digilent power accessory, the VRM!

The VRM is a voltage regulator module designed around the Texas Instruments TPS54620 switching regulator.

The input can be connect via male pin header or screw terminal providing multiple options for battery connection. The outputs can be accessed via one screw terminal and a six pin male header, providing numerous possible connections.

It has an input voltage range of 5 – 15V and can step down to either 5 or 3.3V. Capable of providing 6A, and at the small size of .8 inches by 1.5 inches, this little guy is absolutely something to get amped about!

The VRM is designed to provide an interface for a single battery power system for your mechatronics or robotics project. Often in these projects you need multiple voltage levels and have higher current requirements that the AA battery packs can provide. With the VRM you can use up to a 15 V power supply, step it down to 5V and draw up to 6A of current, plenty to drive a system with several types of motors.

The VRM is used in the claw game to power the 3 stepper motor drivers and the Basys3 board.

Basically, if you have a battery, need several different voltage sources, then the VRM is a product to consider. To learn more about the capabilities of the mighty VRM, you can check out its resource center.

About Author

When I started school I wasn’t interested in any of things I’m passionate about now. In fact originally I started out wanting to study art. But then I decided I didn’t want to have people telling me what to create, so I changed to music. Then I decided I didn’t want to ruin a hobby by making it my career. At the same time my Physics class was teaching a unit on the physics of music, and I thought that was way interesting, so I changed to physics. Then by the time physics was over I decided that the coolest part of physics was electricity and magnetism, and I may as well get a degree that transfers directly into a career. So while all this was happening, I was attending Shoreline Community College, and during that time I found my passion, or rather presented itself repeatedly, until I realized, maybe I should take a hint from the universe. While at community college, I was asked to help at the high school by tutoring chemistry students. Then I was asked to help at the elementary school by being a math Olympiad coach. I continued both because I found I really enjoyed it. I also had an opportunity, and was hired to be a tutor in the Math Learning Center at the Community College, a job I really loved. At the same time I was working as a Nanny, which I had been doing for several years, the main reason because I could and would answer the hard questions the kids asked honestly (i.e. why is the sky blue). I then was recommended by the patrons of the MLC to the transfer tutoring center (private tutoring,) and developed a wait list of students. Through all these opportunities at some point I realized that I loved watching people go from totally lost, to masters of a subject. I was also forced to admit that having all these opportunities continually renewed, I must have been somewhat good at it. So I decided I wanted to teach, which fits with my mission oriented personality. I saw a serious lack of passionate ECE professors in the institutions I attended. At WSU I continued this trend by being ask to TA for computer science and electrical engineering, being a TA for a total of 4 semesters. This continued by getting an amazing opportunity in my first semester at Washington State University to work at Digilent, an educational company. So even if I didn’t want to teach, turns out I can’t avoid it. Luckily it is my main passion.
