TPS7A85: Schematic review

Shlomi Yehezkia

Part Number: TPS7A85
Other Parts Discussed in Thread: TPS7A47,

Hi Team,

My customer made a design “VA608A EMC BOARD” with power supply (DC-DC & LDOs) of TI.

Can you please review the attached schematic and advise/comment on TPS7A85 & TPS7A47?

 

The inductors part numbers:

  1. 1uH - SWSM0603HW-1R0M-F
  2. 1.8uH – 74437346018
  3. 3.3uH – 7447789003

 

Thanks,

Shlomi

    Hi Shlomi,

    It looks like the datasheet recommendations were followed, as such, the schematic looks find per my understanding of the application. Both TPS7A85 and TPS7A47 can be configured using the ANYOUT pins for the output voltages mentioned. As such, you may consider using these as you would no longer need the external resistor divider.

    Very Respectfully,
    Ryan

    Hi Ryan,

    I know that I can use the "ANYOUT" mode, but in this board, there is a possibility that I will need to change the output, in the first option, I prepare to work with feedback resistors.

    Thanks,

    Shlomi
