EYE on NPI – GAPTEC LC78_3.0 Series Switching Regulator #EYEonNPI #DigiKey @DigiKey @Adafruit

This week’s EYE ON NPI (video) is a big time upgrade – we’re featuring GAPTEC’s LC78 series switching regulator modules with up to 28V inputs, 95% efficiency and 3 Amp outputs!

There’s two things we dig about these modules. One, they are pin-compatible with 78xx regulators that we all grew up on. So you can use them to quickly update existing designs from linear to switching power supply. Second, they are extremely easy to use, with ultra-wide input voltage ranges, various output voltages and current outputs if needed.

Why use these instead of just DIYing a switching regulator layout? After all, we’ve covered many great DC/DC controllers on EYE on NPI! Well, to start – laying out and specifying switching regulators is a real pain for folks who are not experienced with some of the pitfalls and it’s very very easy to make a mistake that can smash your regulator or have noisy
output or have less efficiency/output than expected. For some high current outputs, you may need to update to 2 oz copper, 4 layer boards, or have heat sinking vias. If your board is large enough, making the whole thing 4 layer or 2 oz just for the regulator outweighs the cost savings of DIY.

And of course, it’s adorable that these li’l DC/DC bricks are pin-and-size compatible with the standard 78xx regulators that have been used since the beginning of time.

That makes them a good choice when repairing or upgrading existing designs. The GAPTECH LC78’s have much much better efficiency, allowing folks to use a wide range of voltages without worrying about heatsinking or air flow.

I’m a huge fan of these kinds of upgrade modules, because they solve a problem neatly and easily. These have a massive 3 Amp output, a non-trivial amount of current to manage with a linear or DIY switching setup. At that current range these could work great for robotics, large quantities of LEDs, running single-board computers, etc. all in a compact module.

These are available in both 5V LC78_05-3.0 and 3.3V outputs LC78_03-3.0 for immediate ordering. Order the GAPTECH LC78 series modules today, and you could have your power supply up and running by tomorrow morning!

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
