Hi Stephen,
Stephen Karlsgodt said: I purchased this dev board, and it doesn't respond well to the forward phase dimming. The triacs are on all the time, unable to switch off. This is surprising, should the input into the dev board look like a resistive…
Part Number: LM3450AEV120V30 Other Parts Discussed in Thread: LM3450 Hello,
I am using the LM3450AEV120V30 development kit and made a small change to make a new prototype. The change is bypassing the second stage, which is a buck LED driver with LM3409HVMY…
Part Number: LM3450AEV120V30 Hello,
I have started to prototype the LM3450AEV120V30 evaluation board. I could not find the original xformer (750813651) on the design so I decided to use 760871333 from the same manufacturer (WE).
I connected all three output…

Part Number: LM3450AEV120V30 Other Parts Discussed in Thread: LM3450 , LM3409 IN THE PRESENT APPLICATION, THE LM3450 EVALUATION BOARD WILL "SEE" AN 120VAC INPUT WHICH WILL BE 'TRUNCATED' DOWN TO 15V rms. THE SOURCE AC WAVEFORM IS FROM…
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…
Other Parts Discussed in Thread: LM3409 Hi,
I have a design that incorporates the suggested LM3450A-LM3409HV two-stage reference design for an LED driver ( http://www.ti.com/tool/lm3450aev120v30 ). From a national standard of SSL compliance, do you know…
