Part Number: TPS55289 Hi everyone,
Recently I decided the use `TPS55289` for our LED driving application.
However, when I checked the layout recommendation of the IC and also evaluation board `TPS552892EVM-111` I realized that there are copper keep outs…
Part Number: TPS55289 Dear TI-Experts,
Is there a circuit available to protect the TPS55289 from reverse currents caused by large capacitors (1000uF)?
During a test that included no other load than a ~900 uF capacitance and changing the output voltage…
Part Number: TPS55289 hi team:
We recently tested the frequency response of TPS552892QWRYQRQ1 circuit attached, the results shows phase margin (61.7°) and gain margin(13.6db) pass the criteria, but crossover frequency is lower than 10kHz, which means the…
Hi Krishna,
We have not seen an update from you for four weeks, so I assume the questions are answered and the issue is solved.
I close this thread now. If there is still something open, please reply and the thread will get opened again.
If you have any…
Hi Alex,
I think we already have this discussion on the offline email, I will close this thread now. If you have any other question, you can reply on the email or this thread directly and this thread will get opened again. Thanks.

Part Number: TPS55289 Hi Team,
My customer would like to clarify on TPS55289 and related I2C configurable buck-boost converters.
They are concern about the stability of this part. It seems like TPS55289 do not have external compensation loops, so presumably…
Part Number: TPS55289 Hi,
Question 1 When I set the I2C address to 74H and executed WEBENCH, a configuration was generated in which the MODE pin was connected to GND as shown in ② below. The pin function in the datasheet states that when setting it to 74H…
Part Number: TPS55289 Other Parts Discussed in Thread: LM5176 , LM51772 , LM5177 Hi team,
Please recommend a solution of Buck-boost(car standard):
Need to support wide voltage input, 12V output, support >200W, car standard BUCK -BOOST.
