TPS54427: Please help to check the schematic

Part Number: TPS54427


My customer is evaluating  TPS54427 for a 12Vin 1.2Vout 4A design. basically refer to WEBENCH, but a slight difference of the BOM.  so far, they are also evaluating another device , need to confirm this design ASAP.  please help to check this schematic .thanks. 


  • Hi Yue,

    1 recommendation is to increase soft time time to 1.15ms minimum, which mean you need to increase C467 from 6.8nF to 8.2nF.  

    Also, I don't see input and output capacitors, so please follow and use the recommended values from the datasheet.  The rest of circuit seems OK.  Thanks
