by Susan Nordyk @ edn.com: Housed in a tiny 3×3-mm QFN package, the MIC24046-H synchronous step-down regulator from Micrel offers efficiency of greater than 90% peak and pin-selectable output voltage, switching frequency, and current limit. A wide input voltage range of 4.5 V to 19...

by Graham Prophet @ edn-europe.com: LT8494 is a current mode, fixed frequency SEPIC/boost DC/DC converter with an internal 2A, 70V switch. Quiescent current of 7µA suits the device for always-on automotive or other industrial battery powered systems. The LT8494 starts up from an...

by Valentin Kulikov @ edn.com This article describes simple constant current driver module with fast PWM input that can be used for driving medium and high power LEDs. The module uses an integrated constant-current output, DC-DC buck converter with output current configurable from...

A programmable 8-character LCD module and digital voltmeter project from Tuxgraphics: Our 3 digit LED digital voltmeter module has been quite successful over the years. This new LCD module is basically an advanced version with a lot more capabilities. You can power it with the same...

by Sagar Savant @ edn.com: Choosing components is a series of time-consuming tasks, from surveying the market for possible candidates to properly evaluating performance. As a hardware engineer who has worked in Silicon Valley for 10 years, I have spent significant time developing...

If you need to simulate overvoltage, slow start, fluctuations and other situations, which may occur in real life, then the TDK Lambda power supplies won´t disappoint you. Imagine a laboratory (testing) power supply able to provide a virtually any function. Switching on, drop-out,...

by Aleator777: What's that smell? It's noxious gas of course! If you're in an environment where there's a possibility of gaseous release of which you'd rather not breathe, why not build an automatic system for sensing and alerting you? The design for the Environmental Alert System is...
