Part Number: TPS53355 Hi;
We are developing a DCDC power at 1V/10A for our FPGA and using tps53355,following is the schematic:
We use 2 47UF ceramic capacitors at Vin and 7 100UF at Vout. The output inductor is 0.47uL. Cr is 100nF and Rr is 3.01k…
Part Number: TPS53355 Hello:
The output voltage of the TPS53355 chip designed by the customer is 3.3V. On the faulty board that was repaired, the output voltage of this chip is 0, and the LL pin of the chip has been short circuited to GND, resulting…
Part Number: TPS53355 Dear TI Support Team,
We are experiencing a critical issue with TPS53355DQPR on our test board and require your expert assistance in diagnosing the problem.

Board: 2-layer FR4 test board (functional verification…
Part Number: TPS53355 Hi;
I am designing a DCDC power for FPGA VCCINT=1.0V, we need a 12A current. I use tps53355 design.xlsx to do my design. I filled the numbers requied, it seems everything is OK, but the line 'f_ESR' turne yellow, I don't know how…
Part Number: TPS53355 Dear TI Support Team,
I am writing to seek your technical guidance regarding an issue we are encountering with the TPSS3355 buck converter in one of our board designs.
During testing, we observed the following behavior:

I would like to know can datecode be traced via body marking from IC MPN#TPS53355ADQPR?
Body marking: Ti381" and "Ti611"
May I know the date code for the ICs with the body markings above?
Part Number: TPS53355 Other Parts Discussed in Thread: TPS54KB20 , TPS548B23 , TPS548A23 Hi;
We found the tps53355 VREG decrease as load current increase:
12A LOAD, VREG is about 4.89V:
15A LOAD, VREG is about 4.31V, and some ripple appeard: …
Part Number: TPS53355 Dear Team,
Request you to verify the schematic. Input 5V, Output 0.84V @ 10A. Please also verify the selected components. Especially Inductor

Part Number: TPS53355 Hi
When the load is heavy, and the output voltage is normal, PGOOD will pull low for about 1ms. What could be causing this problem? Later, we tested and removed C5 from the circuit, and the problem disappeared. What is the function…
