LTC7851 – Quad Output, Multiphase Step-Down Voltage Mode DC/DC Controller with Accurate Current Sharing
https://www.electronics-lab.com/ltc7851-quad-output-multiphase-step-voltage-mode-dcdc-controller-accurate-current-sharing/
The LTC7851 is a quad output multiphase synchronous step-down DC/DC controller with accurate current sharing between phases and differential output voltage sensing. This controller works in conjunction with external power train devices such as DrMOS and power blocks as well as discrete N-channel MOSFETs and associated gate drivers, enabling flexible design configurations. Up to 8 […]
Opto-isolated laser controller build
https://www.electronics-lab.com/opto-isolated-laser-controller-build/
Scott Harden built his own opto-isolated laser controller and wrote a post on his blog detailing its assembly: My goal was to utilize a free hardware output line to signal to a device that I build to modulate the laser in a special way. This way there would be no modification to any existing equipment, […]
LT8391 – 60V Synchronous 4-Switch Buck-Boost LED Controller
https://www.electronics-lab.com/lt8391-60v-synchronous-4-switch-buck-boost-led-controller/
The LT8391 is a synchronous 4-switch buck-boost LED controller that regulates LED current from input voltage above, below, or equal to the output voltage. The proprietary peak-buck peak-boost current mode control scheme allows adjustable and synchronizable 150kHz to 650kHz fixed frequency operation, or internal ±15% triangle spread spectrum operation for low EMI. With 4V to […]
RGB LED Strip Controller

Thomas Gonnot has published a RGB LED Strip Controller based on STM32F0 microcontroller. The controller is able to power NeoPixel and DotStar protocol RGB LEDs. A simple controller for a RGB LED strip, with independent control of color and intensity. The design is based on a simple STM32F0 microcontroller. It can handle NeoPixel and DotStar […]
LTC7813 – Low IQ, 60V Synchronous Boost+Buck Controller
https://www.electronics-lab.com/ltc7813-low-iq-60v-synchronous-boostbuck-controller/
Linear Technology Corporation introduces the LTC7813, a dual output (boost + buck), low quiescent current synchronous DC/DC controller. When cascaded, its independent step-up (boost) and step-down (buck) controllers regulate the output voltage from an input voltage that can be above, below, or equal to the output voltage, including during an automotive load dump or cold […]
Smokerduino – Arduino Smoker Controller
https://www.electronics-lab.com/smokerduino/
rjkorn @ instructables.com shows us his Arduino Smoker Controller: I had made a Sous Vide controller and thought it might work well for my smoker too. All I really had to do was change the sensor form a Dallas 18B20 to a thermocouple. The Dallas sensor tops out at about 250 degrees Fahrenheit. This particular smoker […]
Simple, Cheap Motor Controller
https://www.electronics-lab.com/simple-cheap-motor-controller/
by TeamJaeger @ instructables.com: I’ve used this simple circuit several times to drive motors (like in my Stair Climbing robot) as well as solenoids. I originally picked it up from this instructable which is focused on controlling a solenoid. I wanted to isolate this circuit in its own Instructable as a motor driver so I could […]
Arduino Time-Lapse Panorama Controller
https://www.electronics-lab.com/arduino-time-lapse-panorama-controller/
by oliverb @ instructables.com: The Arduino controls a Geared Stepper Motor 28BYJ-48 via a ULN2003 Stepper Motor Driver Board. The 4×20 I2C LCD display and 5 micro switches form the interface to the Arduino. The controller has a Manfrotto 200PL-14 quick release tripod mount for attachment to my tripod and other mounting hardware fitted with a […]
Arduino-based “Analog” slow cooker controller
https://www.electronics-lab.com/arduino-based-analog-slow-cooker-controller/
Dan Ternes blogged about his Arduino-based controller for analog slow cookers: With the AC power control figured out, I considered the User Interface. I opted for something simple. The Adafruit RGB LCD Shield would work well as it had both a display and buttons built in. Sure, I could have beat this project about the […]
