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,
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 cut dimming…
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 conducting…
Part Number: LM3450 Hi Team,
I have the LM3450AEV120V30 kit , I have a question about that controller:
The Holding current mechanism is the bleeding circuit that sink current from the Dimmer to maintain proper work with Dimmers.
The disadvantage with…
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.

Hi Stephen,
Thanks for your patience.
Stephen Karlsgodt said: My question: Would it be possible to use the LM3450 and LM3409HV combination (like found on the LM3450AEV120V30) to drive our max LED load of ~150W?
I think it is possible to drive a maximum…
Part Number: LM3450 Other Parts Discussed in Thread: LM3409 , Hello,
Our power supply is based upon LM3450A having LM3409 on secondary side. On Primary side we don't use dynamic hold functionality comming with LM3450. So Pin "HOLD" is floating and Pin…
Part Number: LM3450 Hi,
Please find attached files showing our power factor problem. I have modified the Demo board "LM3450 Design Guide" to be a single stage design with 14V output. I get good power facotr up to about 90Vac input, after that…
