LM36274: Question about LM36274YFFR

Hi Jimmy,

The customer connect LCM_EN1 and LCM_EN2 to ground, so they don't need the VSP and VSN?

Hi Patrick：

1、The customer planned to use I2C control to save GPIO, so it was grounded.

2、Please check the location of the backlight VIN, as shown in the picture, with RC filtering added? Could you please check if it is possible

3、In addition, The screen backlight specification is 6 series and 3 parallel, and the planned maximum backlight current is 20 mA per channel, totally 60 mA

The inductance specifications are as follows. Would you please check if they meet the requirements,Thanks!!!

Hi Patrick：

Please check about the location of the backlight VIN, as shown in the picture, RC filtering is added.

Could you please check if it is OK, Thanks!!!

Hi Jimmy,

I think the RC is ok, but it is better to follow the datasheet.
