Thank you in advance for your feedback and support regarding my request.

Hi Oumy-san, could you help to offer the Vin voltage range and the EE of this project.

Hi Frank,

Vin = 5V. What do you mean by EE?

Thank you for your feedback.

Hi Oumy-san, EE means End Equipment. And for the Vin, there may be a range in normal condition, could you confirm the input is constant?

I see. The Led driver is for a 7" LCD screen with the backlight settings I gave you in the first chat. If it's not enough for the EE information, what do you want to know?
For the input voltage, I confirm because it is supplied by direct external power.

Note: my name is just Oumy :).

Hello Oumy

Any requirement on dimming mode? Based on existing requirement, I think TPS61177, TPS61176 both fit for this application.
