We've been searching for the route cause like the below.
1. +12VIN-EPAD / +12VIN-PGND almost shorten (ohm analysis in the picture) in TPS548A20(which is 3.3V source) in case #1 Board.
2. IN that board : CPU uses its power source from 1.05V and 3.3V…
Part Number: TPS548A20 Hi Team:
Customer use TPS548A20 for low noise RF case, can you help to review attach SCH and layout?
tks advance.

Part Number: TPS548A20 Hi team:
can you help to send the IBIS model for TPS548A20 device to me? My customer want it for PI and SI simulation。
tks for your checking.
Part Number: TPS548A20 Question 1: Output Capacitance Range:
The datasheet indicates that we should try to set the 2-pole L-C filter at a frequency at or below the internal zero frequency (between 6 and 12kHz). This approach results in an unrealistically…
Part Number: TPS548A20 Hi,
We are using TPS548A20 to generate 1.0V @ 10A from 12V.
1.0V goes to Load(MPU) from regulator,
Vout trace which connects feedback resistors(Rtop,Rbot) is coming from Load side in Internal Power plane. This power plane has one…
Part Number: TPS548A20 Hi Team,
Currentaly I am using TPS549A20RVER in our design. Looking another part from TI e.g TPS548A20RVER as an potential alternate. In our current design PMBUS of TPS549A20RVER device has not been used.
TPS549A20RVER and TPS548A20RVER…
Part Number: TPS548A20 Hi,
On the page #6 of TPS548A20 data sheet, i saw "PGOOD in from higher", "Delay for PGOOD going in",
can you tell me what " PGOOD in" and "Delay for PGOOD going in" means?
Thanks,
Tony
