    Hello,

    No.
    The switch current limit for the TPS61291 is 1A.

    The application that you are asking about will require a solution that has a device with a higher switch current limit.

    I would recommend looking at the TPS610981 or TPS610982.

    What I would recommend is going to the product page for one of these devices and input your circuit requirements into the webench tool on the right side of the screen. This tool will allow you to simulate the operation of this part to test to see if it will work for your configuration.

    Hello
    TPS61291 can't support 1A output current. please have a look at TPS61021A for your application.
