Schematic review: TPS53355; TPS51206; TPS54320RHLR; TPS73701DRVR

Dear,

Can anyone help us review this schematic?

Thanks

Tung

I took a quick look at the TPS54320 schematics.  You did not supply any design equations, so I only looked for obvious errors or component values that are much lower or higher than typical.  I do notice that your 5 V, 3A supply has only 2 x 22 uF of output capacitance. The supply will regulate with that, but transient performance may not be optimal.

Hi John Tucker,

I do not understand your meaning "You did not supply any design equations".

Our CPU accept voltage ripple less than 5%. Could you please help review again.

Thanks

Tung

How did you determine the component values?  I'm sure you used some equations.  If you provide those I will check them.  Otherwise the schematic review is a "visual inspection" to look for obvious errors.

Hi John Tucker,

I used SwitcherPro Desktop.

Thanks

Hi John Tucker,

Did you take time to review my schematic?. We're going to build some prototype boards, please help!

Thanks

Tung

Hi Nancy,

Could you please review my schematic? We're going to build some prototype boards next week.

Thanks

I did look at that schematic previously and provided my comments.  The TPS54320 is not a part that I directly support, but sometimes I will comment on general topics if I know about them.  usually, it is best to contact your local AFA or FAE to get schematic reviews.
