Part Number: TPS54620 I have been trying to track and debug an extremely odd system failure on a PCIe add in card and after a long frustrating incremental process of debug have determined that at least one of the points of failure is in the power system…
Part Number: TPS54620 Hi,
Is there a document explaining the fault mode of TPS54620? such as the impact of short circuits or open circuits on the output of each pin.
Thanks!
Part Number: TPS54620 Hi TI experts,
In our design, there is an uncontrollable high pulse (3.3V) applied to EN pin before normal power up sequence starts.
The pulse width is about ~10ns. Is there any deglitch filter inside TPS54620 EN pin which can filter…
Part Number: TPS54620 Hi All,
I have a question regarding the EN terminal of TPS54620.
What is the internal pull-up resistance of the EN pin?
Best Regards, Ishiwata
Part Number: TPS54620 Hi team,
My customer is using our TPS54620.
Could you please kindly help check below two questions:
1. How to choose TPS54620 EN pin Vstart and Vstop ?
2.Vstart and Vstop means which pin's voltage? ( Ven or Vin )
Thanks,
Brian
Part Number: TPS54620 Hello,
The question is from my customer: When I was using the TPS54620, I noticed that the oscillation in the figure below occurred during the power-up process. O scillation will decrease when I minish the Cap connected to SS/TR pin…
Part Number: TPS54620 I'm trying to design an inverting buck-boost using the TPS54620 for an aerospace application.
1. Imported the unencrypted SPICE model into LTSpice (only available SPICE software at my current job). Simulation seems to work fine…
