Hi Yihe,
Please accept my apologies, you can close this ticket. We've found a bug in our smbus block write implementation, I thought this had been checked but it seems this was not the case. NVM writes are working successfully now.

Part Number: TPS53681 Dear Team,
customer is using TPS53681 for Radio design, and they found TPS53681 can not work at -40C.
at -40C, Vin12V, and Vout 5.35V is ok and Vout 0.85V can not work.
if TI has any solution ready to resove the issue for low temperature…
Part Number: TPS53681 Other Parts Discussed in Thread: TPS53689 , TPS53688 Hello expert,
My customer would like to program IC on board with MCU, may we know if you can provide the program process for us? Based on TPS53688 and TPS53689, I have the programming…
Part Number: TPS53681 Hi team,
What command will be returned if FAULT is cleared to TPS53681 through PMBUS?
After writing the 03 command on the customer's board, NACK is returned. Is it because 53681 did not receive the 03 command?
In addition, does…
Part Number: TPS53681 What is the voltage threshold for the TPS53681 AVR_EN, BVR_EN, and Reset pins? The datasheet only has recommended operating conditions of -0.1V to 3.5V.
Part Number: TPS53681 Hi team,
When I programmed TPS53681, the programming was unsuccessful due to below error. I’ve attached the file. The output file was created under offline mode.
On the problem, we reproduced the .csv file by using old version…
Part Number: TPS53681 Hi,
For below EN threshold, does it mean the controller can be enabled once EN>=0.8V, and disabled once EN<=0.7V?
What's the status of the controller when EN is between 0.7V and 0.8V? given EN voltage rises and falls slowly…

Hi,
What is the default output voltage from a brand-new TPS53681?
For our mass production, how can I set the desired output voltage before power up the board?
Thanks,
