Dear team,

Could you please help recommend one appropriate device to support below LCD specs? VIN=VDD=3.3V, there are four output voltages as below.

Thanks & Best Regards,

Hello,

this specification is for a bipolar source supply as well as gate on/off supply. I would suggest to use TPS65131 along with discrete charge pumps for VGH/VGL. There is referee design for such design and you can find it by searching for “PMP9780”.

Kind Regards,

Liaqat
