A modification of the current-control circuit in a low-voltage LED system allows use of a chopped supply voltage to modulate the LED intensity. The circuit prevents inrush current to the decoupling ...

This presentation was originally given by Andrew Smith, product manager, LED Lighting at Power Integrations for EDN’s May 2011 live LED event in San Jose. Consumers often see LED lamp failures. If you ...

Could a single memristor replace both the driving transistor and storage capacitor in micro-LEDs? Prof. Tae-Geun Kim and team ...

Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...

Look at almost any circuit, and it’s nearly sure that there will be a capacitor included in it. These two-terminal electrical components rank alongside resistors.

Teardowns of cheap electronic devices can produce results that are interesting, horrifying, or both, especially when mains power is involved. [bigclivedotcom] gave a minimalist LED lamp his reverse ...

There’s a part you’ll find in almost every mains powered switch mode power supply that might at first appear to have only one application. An optocoupler sits between the low voltage ...

A small LED angle on this one – AVX has developed what it claims is the first 63V and 75V single-anode tantalum polymer capacitors, writes Richard Wilson. The capacitors feature reduced ignition ...
