Hi , 

I am currently using LMR14020, for converting 24V to 5V , however , I wish to generate a isolated 5V for the same , so I have replaced inductor with Flyback transformer , please refer the circuit for the same and comment whether will it work or no , I have run simulation on Tina .

    Hi Gaurav,

    L1 must be DNP.  T1 can be a 1:1 coupled inductor.

    Now the T1 connection is not correct, you need to exchange terminal 9 and 6.

    Another key point is: 5V_ISO maximum load current should be 1/5 or even lower of 5VDC_BRD minimum load current. so does it on output capacitors.
