Part Number: LM3447-PAR-230VEVM Other Parts Discussed in Thread: LM3447-A19-230VEVM Hi,
As per LM3447-PAR-230VEVM Schematic, rectified AC is connected to transformer pin no.1 and is connected to signal ground...
is it correct?? or transformer pin no 14…
Hi Krupali,

page 11, fig12, you show input current. But I have not obtained this current, The input voltage and current graph is in the following link…
Part Number: LM3447-A19-230VEVM hello i was wondering if someone could explain me the unusual LC filtering configuration used in the emi filter. It resembles a 4th order LC filter but is placed across the ac input.
The shape of the current is shown in the figure. This is the minimum level of brightness. We conducted tests on another load (15W) using LM3447-PAR-230VEVM. At the minimum dimming levels, there are also minor changes in brightness visible to the eye. As…
Hello Irwin,
In reality its not the transformer that is causing me the problem, its the massive capacitor on the primary side... if only it were on the secondary side there would be no issue.
I have seen other reference designs, for example, www.ti…
