EVBUM2175DB - 3.6 W Flyback 3 LED Step Dimmable Driver Evaluation Board User's Manual
ON Semiconductor
This documentation package covers an NCL30081 LED
driver for use in a GU10 based LED lamp. The output is
mains isolated by double insulation. Maximum input power
is 5 W. The ECA (Electronic Circuit Assembly) supports 2
versions; one step dimming and one non-dimming version.
The version is controlled through minor bill-of-material
changes. The LED current dims in 5 discrete levels
sequentially by detecting the interruption of the AC mains
briefly (about 1 s) to step the LED current down one level
until it cycles back to full current.
