The customer configure the TPS55010 to Fly-buck,but see the high voltage stress at PH pin during the secondary winding short testing.
Seems there is no internal low side Mosfet current limiter of TPS55010.
Pls advice whether the TPS55010 can support the Fly-buck.
And any solution/idea can provide the protection for the secondary winding short testing.
