  Hey Bindu, The conversion from 5.2V to 3.3V at 3A load will cause the device to enter thermal shutdown. Please lower the power dissipation across the device. The PG pullup resistor in the schematic should be greater than 10k. Please remove the PG resistor…

  Resolved

  Part Number: TPS74901 Hi team, As we know that the VBias must be 1.75V above Vout. In this case, Vbias need at least > 3.35V(1.8V+1.75V = 3.35V). but the board doesn't have 5V source. Could we use resisters to divide 12V source to 5V for VBias? If…
