Part Number: LM3648 Hello
I'm looking for a driver that handles up to 500mA for driving high power leds. I found this LM3648TT but my question is: could this driver be used also with RED leds?

Hi Wayne,
There are two solutions for you:
1. LM3644 which is the two-channel flash LED driver and you can use each channel to two or three LEDs it seems the forward voltage is less than 4V which is less than the OVP threshold;
2. LM36010+LM3648…
Dear Sean,
For LM36010, customer found another similiar part no.---LM3648, also can support this requirment. What's the difference about these devices, which is more popular? Thanks a lot.

Greg,
Thank you for your reply. LM3648 will be a better solution from the data sheet description. But from the data sheet, I can't see exactly how fast the response of LM3648 is. Will LM2759 have similar repeated pulse on/off performance as LM3648…
Part Number: LM2759 Other Parts Discussed in Thread: LM3648 Hello, I have questions about I2C of LM2759.
(1) I2C specification In the datasheet, there is few I2C timing specifications only. Can we use this device on the following I2C specification which…
