3W Stereo Audio Amplifier using TDA7266D
https://www.electronics-lab.com/project/3w-stereo-audio-amplifier-using-tda7266d/
Tiny stereo audio amplifier board has been designed around SMD TDA7266D IC from ST. The TDA7266D is a dual bridge amplifier specially designed for Portable Audio, LCD TV/Monitor, PC Motherboard, and TV applications. This circuit provides high quality audio output of 3W approx. on each channel with standard audio signal input. The circuit works with […]
Raspberry Pi Web Server using Flask to Control GPIOs
https://www.electronics-lab.com/raspberry-pi-web-server-using-flask-control-gpios/
In this article “Rui Santos” shows us how to configure Raspberry Pi as server and use it to toggle two LEDs over the internet. In this project you’ll create a standalone web server with a Raspberry Pi that can toggle two LEDs. You can replace those LEDs with any output (like a relay or a […]
Hot rods keep the die cool
https://www.electronics-lab.com/hot-rods-keep-die-cool/
Clemens Valens @ elektormagazine.com shows us a new IC Package that keeps the IC cool. Texas Instruments’ HotRod QFN is a thermally enhanced plastic package with solder lands on all sides as well as power buses for enhanced current carrying capability. Inside the package the die is mounted on a copper lead frame which eliminates the […]
0.8A step-up DC/DC converters in a tiny package
https://www.electronics-lab.com/0-8a-step-dcdc-converters-tiny-package/
Torex Semiconductor’s XC9141/XC9142 series of 0.8A step-up DC/DC converters come with an input–output disconnection function (load disconnection function) to prevent malfunctioning during standby, and for device functionality that enables power supply to RTC. When the output voltage is 3.3V, the IC can start from an input voltage of 0.9V with a resistance load of 100Ω, […]

13.8V 2A Power Supply using LM338
https://www.electronics-lab.com/project/13-8v-2a-power-supply-using-lm338/
Introduction This power supply appeared in the summer issue of Elektor 2000 without a PCB layout. So, I decided to build a PCB using Cadsoft EAGLE Lite edition following the Elektor’s schematic and introducing some changes. The power supply uses through-hole parts which are easy to find on market. Main part is LM338 Regulator which […]
