Part Number: TPS54527

 Dears,

The spec of TPS52527 shows that output voltage is 0.76-6V,but customer design Vin 12V&Vout 9V,then they found the inductor is burned,rated about 25%.Detalis pls find below information:

1. Vin12V,Vout 9V,this design is correct or  not? Customer'S  product has been shipped for one year, and the market has not reported any defects related to the TPS52527.

2.Is the inductance damage related to the design of this circuit? The specification of inductance is the chip inductance CHP5020B-1R5Y 1.5uH 4.1A with ±30%.

Pls kindly help to confirm.

Thanks
