Part recommendation for TFT LCD driver

Louie

Hello,

I am looking for a low power recommendation for driving a 150mm x 150mm TFT LCD screen.

Using a 3.7V, 2Ah battery, can buck or boost, but currently only using a buck to 3.3V rail. 

Thank you,

John Louie

    Hello Louie,

    Thanks for your request. Could you please provide information on the electrical requirements for the LCD screen?

    Best Regards.

    Hello,

    The only electrical requirements that I have for this is that they would like the rail to be at 3.3V.

    They are using a 3.7V, 2Ah battery. They will have a few other things on there, so something that is both cost and power efficient is preferred.

    Thank you,

    Louie

    Hello Louie,

    So you have a 3.7V LiIon battery as supply and need a 3.3V supply derived from this to supply an LCD module. Please check the current that is needed from the LCD and then you should find a fitting part in the buck-boost converters:

    Best regards,
