LMG3411R050 : I want to activate boost mode

Part Number: LMG3411R050
The buck mode works normally, but when operating in boost mode, it takes cc and heats up the fet just by connecting input power. I made a general synchronous buck converter circuit and put a capacitor of 80V / 660uf at the 200V / 100uf output at the input. I want to analyze both buck mode and boost mode, but I would like to explain how to activate boost mode.
  • Hello Yong Sung,

    There is nothing that you need to do to switch from buck mode to boost mode. Simply reverse the input and output source and load on the two sides of the converter can make it happen. Thanks!

    Best regards,
