    Part Number: LM5160DNTFBK-CALC I think "Maximum Recommended Value for Rr" is calculated so that injection level becomes 50mV. I heard injection level should be 20mV to 50mV. Injection level decreases as Rr value increases. So I think this "Maximum…

    Hi, From the schematic you showed, the transformer ratio is 2:1 and you want both Vpri and Vsec to be 12V which conflicts. Please confirm and send us a complete flybuck calculation tool and we can check the settings accordingly. https://www.ti.com/tool/LM5160DNTFBK…

    Hello, It would be better to visualize all of your design parameters with you populating them into the flybuck calculator for this IC. The calculator performs the same calculations you have already done and comes up with component values. My hope is we…

    Hi, Because fly-buck is a primary feedback topology, the output voltage will be changed by you diode and path resistor. So please change D1 to another diode with lower forward conduction voltage drop. You can also use the excel tool to calculate component…

    Hi, This looks like some kind of instability. Do you use the same value as webench recommend on R50 and C37? You can also check the ripple injection circuit value here http://www.ti.com/tool/lm5160dntfbk-calc You can maybe try to lower the R50 and see…
