    [PIC] SG3525 Low output voltage

    Hi everyone, can someone help me?, I am using SG3525 for my Push Pull inverter design but each time I design it I get voltage not up to 220v, maybe 201v even if I had Feedback to My circut. Can anyone tell me the Adjustment I to do to get a voltage of 250v without Feedback. Thanks
