Part Number: TPS543B20
Hello Team,
I've incorporated the TPS543B20RVFT into my design to supply power to the FPGA. Ideally, the output voltage from the IC should be 0.85V. However, I'm finding it to be 0.9V initially, and after programming the FPGA,…
Part Number: TPS543B20 Hello,
We have designed a power supply for the FPGA using TPS543B20 device. The output voltage requirement is 0.85V @ 20A. Input voltage supply is 12V. We have followed the schematic as per WEBENCH simulation . The schematic is…
Part Number: TPS543B20 Hi expert,
My customer has some questions on 5V input application.
If the Vin is 5V, what is the output of BP pin?
Following from question 1, is there any limitation to use 5V for input?
Thanks,
Oliver
Hi Britton
Thank you for that, but there are a few things I would like to clarify and explain more to the customer.
Britton Jones said: 1. See explanation above. One possible reason that we see the 'multiple hiccups and then successful start-up behavior…

Part Number: TPS543B20 Hi expert,
From datasheet 8.4.14,
1. We would like to check that OVP the hiccup restart, does that mean the device keeps restarts until the restart successfully? Otherwise, device will keep trying.
2. About the UVP, does that mean…
