The LTC3639 step-down regulator integrates key high performance features into one compact IC. It is capable of up to 150V input voltage and 100mA output current, utilizing synchronous rectification and low quiescent current to maintain high efficiency over a broad spectrum of load current. Its adjustable output can be programmed from 0.8V to VIN, while […]

Inspired by trees scientists at the University of Maryland have developed a nanobattery that uses tin-coated wood fibers to store liquid electrolytes. Replacing the lithium found in many rechargeable batteries by sodium makes the battery environmentally benign. Sodium doesn’t store energy as efficiently as lithium, so you won’t see this battery in your cell phone […]

Today we present you a  stereo 10 + 10 Watts  audio amplifier based on TDA7297SA, a monolithic dual bridge amplifier that is suitable to be used in projects that feature access to a single 12 volts power supply. This is a compact stereo amplifier: its field of application range from car stereo to portable audiovisual […]

AUSTIN, Texas–(BUSINESS WIRE)–Silicon Labs (NASDAQ: SLAB), a leader in high-performance, analog-intensive, mixed-signal ICs, today introduced the industry’s most highly integrated MEMS-based oscillators designed to replace general-purpose crystal oscillators (XOs) in cost-sensitive, low-power and high-volume industrial, embedded and consumer electronics applications such as digital cameras, storage and memory, ATM machines, point-of-sale equipment and multi-function printers. The […]

Description. The circuit given here is of a very useful and accurate digital voltmeter with LED display using the ICL7107 from Intersil. The ICL7107 is a high performance, low power, 3.5 digit analog to digital converter. The IC includes internal circuitry for seven segment decoders, display drivers, reference voltage source and a clock. The power […]

Pong was the first ever videogame that reached the mass market. For the first time in history, the concept of a “video game” was brought into the family home, thanks to the Atari 2600 – so it’s only right that we pay a little homage to this historical gem. Now, you can re-live that (admittedly […]

Just for the fun of it I’ll try do design and order a Seeedstudio 5×5 cm PCB every week. I’ll do the design and layout during the week and weekend and then submit the order on Monday. I’m not 100% sure that I’ll actually will be able to do this every week, but I’ll try […]
