    Hi John:

      1.Our application input AC24V ,output 60V 100W ,

    2.We are use Excel calculator and modify EVM board some of  component value (ICOMP,VCOMP) base on calculator result .

    3.When loading 100mA seem OK ,but increase loading to 300mA will cause UCC28180 not working ,output voltage equal to input voltage

    Would U help check our Excel file contain correct or not

    Thanks
