Hello,
You should look at the LM3450 (non A) version. The 'A' version will always add load. A lot of this is explained in the datasheet (see page 26 as well as reading about all the differences between the 'A' version and the 'non-A' version in the…
Part Number: LM3450 Hello, I'm trying to convert a dual SCR based Triac 24V AC halogen fixture to LED, I have spent a long time with EE's trying to solve, trying to decode with Arduino, this works with anomalies, but an IC may be more appropriate. I am…
Part Number: LM3450 Hi Team,
My customer see something is the LM3450A that make them wonder if this is the right way to work.
The Controller switch the MOSFET, of the flyback, on even when there is no voltage detected.
It means, the MOSFET is…
Part Number: LM3450 Hi,
I have a customer looking to use this device for a variety of low-mid power PSUs up to 277VAC.
they wanted to confirm whether this device can be used with no phase cut dimming in a universal mains product with 120V phase…
Part Number: LM3450AEV120V30 Hello,
I was not able to find the same transformer 750813651 as in "AN-2150 LM3450A Evaluation Board".
There was a recommendation to use 760871333 in the following link.

Hello Steve,
Are you using this as a current regulator? Normally single stage LED drivers regulate current. If not and you are just creating a single stage voltage output it looks like the bandwidth may be too high. Try lowering the bandwidth of the…
Hello,
I can try and help you figure this out. How are you using the LM3450, as a power factor controller from rectified AC? What are you doing with the dimming pins on the part? I see some of the history of this post, is this still relevant? Are you…
