22,000 power supplies now located in the Dallas Cowboys stadium
There has been a lot of TV coverage recently concerning the Dallas Cowboys giant video displays at their new stadium in Arlington. The $40m, four-sided, high-definition Diamond Vision video board, which is built by Mitsubishi Electric, uses 22,000 TDK-Lambda ZWS power supplies to light the 25 million Light Emitting Diodes (LEDs) needed to create the image on the screen.
Constant-current LED driver features 16 channels and 7-bit dot correction
New from Allegro MicroSystems Europe is the A6285, a 16-channel constant-current LED driver featuring individual channel current adjustment via a 7-bit dot correction register. Each channel of the A6285 can sink a constant current up to 80 mA, and a single external resistor sets the maximum LED drive current for all channels. Each channel's drive current can be individually adjusted from 0 to 100% of the maximum value via the dot correction regi...
