    Hello Vivek,

    Do you mean that the circuit you posted does not work and the input current is too high?

    Can you please tell us what you observe? What are the output voltages, the voltage on FBN/P and the input current you measure? If you have scope plot of the startup, please post it.

    I noticed that for the inductance and output capcitances you are using different values than the one recommended in datasheet. Can you increase the output capacitors to 22 uF and use 4.7 uH inductors (see D/S page 13 and 14 for details).

    Best regards,

    Diaara
