TPS65131/about calculation sheet

Other Parts Discussed in Thread: TPS65131, TPS65130

Hi,

Could you tell me about TPS65131?
My customer is considering TPS65131.
Customers want information other than the data sheetin employ display driver.
Do you have a calculation sheet and circuit design material?

Best regards,
Yusuke/Japan Disty

    Hello Yusuke,

    What exactly do you want to calculate? The datasheet provides all necessary formulas that you need to design a positive and negative output voltage. Can you provide what display your customer is using and what are the requirements for this?
    What is the end application?

    Thank you.
    Best Regards.

    Ilona-san,

    Thank you for your response.
    I apologise for the delay in replying to you.

    I will describe the required specifications of the customer.
    ・Panel：5.2inch LCD
    ・Vpos=5.4V(typ) / sourcec current=50mA
    ・Vneg=-5.4V(typ) / sink current=-50mA
    ・Vin=3.3V

    Customer is wanting a calculation sheet or design materials.
    Could you give me advice?

    Best regards,
    Yusuke/Japan Disty

    Hello Yusuke-san,

    First of all, as your application only requires 50 mA at 5.4 V I recommend to use the TPS65130 which comes with a smaller solution size. You do not need the high saturation current of the inductor in the TPS65131 version.

    Secondly all required calculation that you will need to design the split-rail supply are described in the datasheet. I recommend that you will work through the datasheet and come back if you have any specific questions.

    For quick evaluation of this device you can order an EVM here.

    Best Regards.

    Ilona-san,

    Thank you for your support.
    I will challenge the introduction of TPS65130.
    However,TPS65131 has been used successfully customer application.
    So,Customer is examining TPS65131.

    I will contact you if I have any questions.

    Best regards,
