    Hello Alex, 

    Using the LM5158x should work for your application. 
    But 1.5A of inductor current will be a bit tough to reach. 
    Either use a pretty high switching frequency of about 1 MHz or switch to the LM5158.

    Please use the QuickStart calculator to find the solution that fits best for you.  

    Best regards
