Other Parts Discussed in Thread: PMP9780, TPS65131

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,

Sherry

    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,
