Part Number: TPS51020 Team,
We need to replace an obsolete output cap that is used with these devices. The new cap has an ESR that is half that of the original. Better for ripple but I want to check to see if it has a substantial effect on the control…
Part Number: TPS54317 Please help ID the datecodes of the TPS54317. These are a little old. Part markings=

Thank you!
Other Parts Discussed in Thread: TPS62290 , TPS54317 We tried creating design of TPS54317 and TPS62290 with WEBENCH. However those circuit were not created. It was not solved though I changed input and output using condition.
Do you have any idea about the…
I don't see anything that jumps out at me on teh schematic. Can you provide some waveforms? Specifically, PH and SS/ENA to start with. You will probably need to trigger on the rising edge of VIN to see what is happening as teh IC attempts to start…
Other Parts Discussed in Thread: TPS54317 What is the role of the Vbias capacitor in TPS54317. 0.1uF is suggested as optimal value for the bias capacitor. What is the start-up implication if we use a low value, say 0.01uF at the Vbias instead of 0.1uF …
Other Parts Discussed in Thread: TPS54317 , SWITCHERPRO TPS54317 parts values are different from Datasheet. TPS54317 D/S says that "VBIAS capacitor is 0.1uF - 10uF". But Switcher-Pro displays "0.01uF".
Furthermore, TPS54317EVM has 41…
