TPS745-Q1: TPS745-Q1 PIN FMEA questions

Part Number: TPS745-Q1

Hi Team, 

my customer is asking questions about the PIN FMEA questions, please kindly help to answer. Thanks. 

1. Package FIT Rate distribution

In the SBVA089 pdf, we have table 2-1 to shows the DIE FIT Rate and Package FIT Rate. For DIE FIT Rate, we have table 3-1 to show the FMD of Die failure mode. Do we have similar data to show the FMD of Package FIT Rate?

2. in Table 3-1, it shows VOUT Not in Specification - Voltage or Timing, 60%. Do we have more detailed data to show DFM in different Vout or timing? Because as you know, the Vout and timing failure will affect the system failure directly. Thanks.

  • Hi Hollis, 

    Unfortunately, we do not have FMD data for specific packages. 

    As for any detailed data to show DFM in different VOUT or timing:

    Failure modes are generated based on knowledge known about the silicon, so we don't have any further information on this either. When it says "VOUT not in specification", this could mean that the nominal VOUT value was not achieved or that it took a long time to reach nominal regulation. 

    Best,

    Juliette
