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 ...

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 ...

Some 1.5 v LED flasher circuits are available on the internet and we like to present you four of them. The flasher circuits below operate on a single 1.5 volt battery. The circuit on the upper uses ...

Capacitors are classified according to their dielectric’s type. Electrolytic capacitors are popular in power electronic circuits, due to their high volumetric efficiency and excellent price ...

With their low equivalent series resistance (ESR), which allows for good ripple-current handling as well as high surge-voltage ratings and self-healing properties, film capacitors are strong ...

With cycling safety in mind, I bought a pair of low power red LED things that replace the bungs in the end of drop handlebars. They are a neat way to get a bit of extra visibility – and to give a ...
