Part Number: TPS548A20 Hello Sir/Mam
We are using TPS548A20RVET in our Design . We need to monitor it's Power good signal so it has to be connected to FPGA with IO Voltage 3.3V. As mentioned in Datasheet it has to pulled high with VREG(5V). So we…
Part Number: TPS548A20 Tool/software: Hi All,
I have a question about the Load Transient of the TPS548A20. Even in FCCM, does the switching period change temporarily at the moment the load changes?
When I checked the data sheet, it looks like switching…
Part Number: TPS548A20 Tool/software: Hi all,
When designing Cout, I understand that it is good to make Fp=1/2π√LC close to the corresponding value of Vsw.
According to Table1, when Vsw=600, 750kHz, Fz is 9kHz below.
I should select the inductor…
Part Number: TPS548A20 Tool/software: Hi,
One of my customers has a question about the TPS548A20. The design checklist shows 120us soft-start time, however, the SPICE simulation suggests a 4ms startup time.
Is there method in we are missing for…

Part Number: TPS548A20 Hello,
My team and I are working on a thermal analysis for our design using ANSYS ICEPAK and I am having a hard time finding thermal models TPS548A20. Currently we are using the thermal resistance values of the ICs from the datasheet…
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
