    I am trying to simulate reference design of ADP5075 in the datasheet, which I included below. 
    

     
    

    I implemented the same design using LTspice except I changed schottky diode as MBRS140.   I did a Dc analysis for the below circuit but I got 0.02V at the output instead of -15V. ı would appreciate if you can tell me what I am missing in LTE simulation.
