A6281
3-Channel Constant Current LED Driver
with Programmable PWM Control
Description (continued)
bus, thus eliminating the need for a separate chip supply bus or an ? Architectural lighting
external regulator.
Applications include:
? Colored, large-character LED signs
? Scrolling, colored marquees
Selection Guid e
? High intensity monochrome displays
? Large video and graphic displays
The A6281 is supplied in a 3 mm × 3 mm 16-terminal QFN (suffix
‘ES’) package, with 0.75 mm nominal overall height. The package
is lead (Pb) free with 100% matte-tin leadframe plating.
