  • TPS54160: TPS54160 Webench results changed from a year ago

    TI Thinks Resolved
    Part Number: TPS54160 Hello, A year ago I used the online Webench to create a 40V to 19V buck converter using the TPS54160DGQ which used the Webench provided ceramic capacitors CKG57NX5R1H226M500JH x 3 and had good gain and phase margin. However when…

  • TPS54160: Abnormal output voltage (Vout)

    Part Number: TPS54160 The LED connected to Pin 6 of TPS54160DGQR lights up, with the output voltage only reaching 4.08 V. Out of 10 circuit boards, only 4 function normally. The 12 V input voltage measures correctly. Where could the fault be located?…
