Tool/software: WEBENCH® Design Tools
Hello,
I am designing a driver for LED CMT2890 (Vf=54V; I=3.3A) using LM3429.
The input:
+ VIN=12V
+ Vled=54V; I=3.3A.
=> Iswitch~20A.
I tried to use WEBENCH but the tool does not support my case. But in the Lm3429 datasheet, it shows that "LED current is not internally limited" so I think LM3429 can work.
If I calculate parts following datasheet of LM3429, can the driver work well with LM3429?
If the LM3429 can't work with my case, can you recommend another part?
Thanks,
Giang
