Part Number: LM25066I

Hi Sirs,

Sorry to bother you.

The question is related to the auto-retry mode and we want to disabled it but HW pin already force to GND

In the first time ,I try to write register (D9H) by PMbus to change to “No retries” it ,yes ,it is work !

So, could we programing (fixed) to “No retries” mode in this part without write register every time during power up ?

Hi Shu-Cheng LIN,

The Default value of D9h register is 0000h. This sets the retry setting, bits 7:5 to 000 which is 'Pin configured retries'.
Unfortunately, we cannot provide a part with different value of registers. So, you may have to program this register every time afetr power up.
