    PI controller using opamp with -ve output


      Dear All,


      I am trying to implement a PI controller for a power converter. Attached is the schematic diagram of the analog part that I want to implement on PSoC-5LP.
      The problem is that PI's opamp output is -ve and opamps in PSoC do not support  a -ve voltage. 
      Any help in this regard would be appreciated.
