Hi Tzannbor,
Thanks for the feedback,
1. From the schematic, I can't see input and output capacitors and also the inductor. Could you share the full schematic of TPS55289-Q1?
2. Recommend to solder the EN pull-down resistor RB16.
3. We need the…

Hi Expert,
I find some difference between TPS55289-Q1 datasheet and real test wave about I2C communication. Below is the photo. When I set the delay time between "ack" and "DATA" as datasheet time sequence, the communication…
Part Number: TPS55289Q1EVM Other Parts Discussed in Thread: USB2ANY , TPS55289 , TPS55288 Tool/software: The GUI can connect with the USB2ANY , but can't connect with the EVM through I2C whatever the addr is 74H or 75H , the TPS55288EVM-530 has the same…
Hi Murali,
For TPS55289, the output voltage can only be enabled after writing 1 to internal OE bit. So without I2C, TPS55289 can't output the target voltage.
And we are going to release TPS55289-Q1 which is optional to output 5V default voltage. You…
Hi Christian,
Sorry for late reply.
1. From my calculation, for 400kHz switching frequency, 36Vin to 1.5Vo is a critical boundary because of min Ton, you can also decrease the switching frequency to get a lower duty cycle.
2. TPS55289 is a full…
Part Number: TPS55189-Q1 Other Parts Discussed in Thread: TPS551892-Q1 , TPS55289 Tool/software: Hi All,
I have a question about the TPS55189-Q1.
Which is effective: setting the EN pin high, or setting the MODE Register (Address = 6h) to 0b (output…
Part Number: TPS551892-Q1 Other Parts Discussed in Thread: TPS55289 , TPS552892 Tool/software: Hello,
I see that TPS551892-Q1 is now yet in Webench as of yet. Can you provide any design examples to aid calculating critical component values?
Thanks…
Part Number: TPS61088-Q1 Other Parts Discussed in Thread: TPS61088 , TPS55288 , TPS55289 Tool/software: Hello,
Anyone knows how to fix the VCC output at 5V? The datasheet is not clear but seems to imply that the output voltage is around 5V but Vin dependent…
