    The fake Chinese chips have laser engraved marking. But the original IR 2153 is marked with white color ink.

    I bought some original IR smd chips and now it works rock solid.
    oh same problem here, too many fake chips

    for softstart I usually use 47 to 100 ohm 10W resistor bypassed by relay

    Fake parts are serious problem indeed, buying from unknown seller over aliexpress will usually get you fake chips.

    You should only buy from trusted sellers.

    Good to hear that you have solved it.

    You guys are wonderful. Thank you all for your help.
    I used this SMPS for a solid state audio amplifier and it works really well.
