5V to 12V @400mA Boost Converter
The circuit presented here is about a boost converter based on LM2698. It is a PWM boost converter from Texas instruments. LM2698 can also be used as a flyback converter. The current mode architecture is a special feature of LM2698, which provides superior line and load regulation. This...

Amplifier requires no dc bias
john guy @ edn.com writes: Intrinsically capacitive transducers and other high-impedance signal sources usually require ac coupling and a buffer amplifier to condition the signal for further processing. Buffers take many forms, but most of them compromise signal quality through the...

5V Regulator Cap for 9V battery
David Cook built a 5V regulator to sit atop a 9V battery: For quick portable projects and temporary hacks, it is often faster to reuse a simple 5V regulator circuit than to integrate a power supply into the device design. My toolbox has an LED tester and magnifier light, so why not...
