LM5168-Q1: FlyBack Transformer recommendation for LM5168 1:1 5V x2

Part Number: LM5168-Q1

Two times 5V are needed with one being isolated. For single output I could use 68 uH TYS6045680M or similar.

I'm not familiar with FlyBack transfomers. Which specific part is recommended in this case to replace the simple inductor for single output.

  • Hi Christian,

    Thank you for consider the LM5168-Q1 in Fly-Buck design. Please choose a coupled inductor, for which you can consider 68uH and 1:1 coupled inductor from Coilcraft or Wurth or other vendors.

    Please note that the Isat of the chosen coupled inductor must support the total power lumped into one 5V rail.

    Thanks,

    Youhao
