LM36011: LED Driver Recommendation for Vf > 6V and 9V

Tool/software:

Hello E2E Experts,

Good day.

Can you suggest any TI LED drivers with a large Vf (>7v, >9v) and is a flash driver? I'm looking for drivers with a dedicated strobe pin or fast responding PWM ideally for a camera flash. Ideally these drivers are QFN or double row BGA like the LM36011, my fab can't reliably do via in pads.

Regards,

Hi,

So the total Vf is about 7V--9V, How about Vin voltage range? and LED current?

Hello Andy,

Vin would be a lipo battery, so 3 - 4.2V. I am not too particular about the LED current; anything more than 300mA is fine, the higher the better.

If no ICs fit the requirements, I'm happy to connect the LEDs in parallel and use the LM36010 to lower the forward voltage, but I'll need to include resistors and lose some efficiency.

Regards,

TICSC
