Part Number: LM3644 Hi team,
I am promoting our LM3644 to our customer. And they are considering using this device in their new projects!
Here is their question about this device:
Can the two LEDs be controlled separately? Both on brightness and ON/OFF state…
Part Number: LM3644 Other Parts Discussed in Thread: LM3648 Hi Sirs,
May I know the LM3644 can connect 2-ch to drive one LED(peak current max = 2A)?
It means we will use it to do the 2nd source device for the LM3648.
Part Number: LM3644 Hi Team,
Just a few question about LM3644 LED driver,
1. Can we drive 1.5A from each LED channel (1.5A + 1.5A, total of 3A) ?
2. If we are not using TX, STROBE & Torch pins, can we left it floating?
Thanks you,
K. Rajesh
Part Number: LM3644 Hi Team, we would like to seek your inputs on this.We need to control the burrs(ripple) in 100mv (3.3V).
Is there any suggestion?
Thank you very much.
