Circuit adds foldback-current protection
by Rafael Garcia-Gil @ edn.com: For many applications that require power-supply currents of a few amperes or less, three-terminal adjustable-output linear voltage regulators, such as National Semiconductor's LM317, offer ease of use, low cost, and full on-chip overload protection. The...

Use an LM317 as 0 to 3V adjustable regulator
by Vladimir Rentyuk @ edn.com: Most engineers know that they can use an inexpensive, three-terminal adjustable regulator, such as Fairchild Semiconductor’s LM317, as an adjustable regulator to only some necessary value of voltage, such as 36 or 3V. This value cannot be less than...

Making the new silicon: Gallium nitride electronics could drastically cut energy usage
by Rob Matheson @ phys.org: An exotic material called gallium nitride (GaN) is poised to become the next semiconductor for power electronics, enabling much higher efficiency than silicon. In 2013, the Department of Energy (DOE) dedicated approximately half of a $140 million...

Have you ever seen a fan resistant to dust and water?
New series of Sunon fans with IP68 protection brings reliability even to conditions, where a usual fan doesn´t withstand too long… Still more noise and vibrations and in extreme case even a total malfunction – this is a typical “end” of the fan after a long-time operation...
