Linear Lab Power Supply with digital meter
https://www.electronics-lab.com/linear-lab-power-supply-digital-meter/
danielrp @ instructables.com build a nice power supply for his lab. He writes: From my point of view one of the best ways to get started in electronics is to build your own laboratory power supply. In this instructable I have tried to collect all the necessary steps so that anyone can construct his own. […]

ThomasVDD @ instructables.com writes: A while back I built a powersupply from an old ATX PSU, and while it works great, I wanted to step up my game with a digital powersupply. As already said, it is powered by batteries (2 lithium cells to be precise), and it can deliver a maximum of 20 V […]
400V – 5A Power Supply For Brushless Motor Drivers
https://www.electronics-lab.com/400v-5a-power-supply-brushless-motor-drivers/
Although the power supply design is specific to the Brushless Servo Drivers mainly for IPM Modules, the concepts and circuit design may be used for any power supply requires high voltage output up to 400V DC and 5 Amps. The power supply is an unregulated design with an option to allow connection to either 120V […]
Reference design – USB Type-C charger delivers 18W
https://www.electronics-lab.com/reference-design-usb-type-c-charger-delivers-18w/
Graham Prophet @ eedesignnewseurope.com discuss about a 18W USB power supply reference design. This joint reference design describes an 18W, USB PD compliant, AC-DC power converter. The design, titled DER-567, pairs the WT6630P USB Type-C PD controller from Weltrend with Power Integrations’ InnoSwitch-CP off-line CV/CC flyback switcher IC, to produce a compact and highly energy-efficient […]
-5V @100mA Switched Capacitor Converter
https://www.electronics-lab.com/5v-100ma-switched-capacitor-converter/
The circuit diagram presented here is about a negative voltage regulator. It is based on LT1054, which is a switched capacitor voltage converter with regulator from Texas instrument. This device has many advantages over other previously available switched capacitor voltage converters. It provides higher current and has lower voltage losses. Features: Input Voltage: 3.5VDC to […]
snapVCC – A snap-on regulated 3.3 V/5 V power supply
https://www.electronics-lab.com/snapvcc-snap-regulated-3-3-v5-v-power-supply/
by Mahesh Venkitachalam @ hackaday.io: I use 9 V batteries for a prototyping a lot of my electronics projects. I was inspired by the Sparkfun breadboard power supply board, and wanted to create something similar, but with a more convenient form factor for use with a 9V battery. The design I came up with, is […]
12V @ 120mA Transformerless Power Supply
https://www.electronics-lab.com/12v-120ma-transformerless-power-supply/
The circuit provided here is a transformer-less non-isolated power supply which is capable of delivering an output of 12V at 120mA current for an input voltage varying from 85VAC-265VAC. The LNK304 is the heart of this circuit which supports buck boost and flyback topologies. This project is low in cost and simple when compared other […]
EEZ H24005, Two-Channel Programmable Power Supply
https://www.electronics-lab.com/eez-h24005-two-channel-programmable-psu/
Envox Experimental Zone (EEZ) is an open hardware and open source development website, that creates and shares various open source hardware and software projects using as much as possible open-source tools and technologies. One of their projects is the programmable bench power supply ‘EEZ H24005’. The goal is to make a reliable, modular, open and […]
PSU Burner – a power supply tester
https://www.electronics-lab.com/psu-burner-power-supply-tester/
Bob @ electrobob.com tipped us with his latest project. It’s about a power supply tester. What does one do when designing a power supply? Well, build a power supply tester, of course. One of the simplest things to build is a constant current load. This will allow for testing of the endurance of the power […]
DIY power supply with 3D printed enclosure
https://www.electronics-lab.com/diy-power-supply-3d-printed-enclosure/
Rui Cabral tipped us with his latest video. It’s about a dual output power supply build in a 3D printed enclosure. Main parts used are a 100W AC-DC converter (110V 220V to 24VDC 6A) and LM2596 DC-DC Buck converter constant current voltage adjustable module. The power supply has two voltage outputs, a fixed 5V output […]
