Other Parts Discussed in Thread: TPS5402
Hi sir,
The customer wants to know why ROSC = GND typ.70khz of FSW of oscillator in the electrical characteristics table on page 5 is deleted when datasheet is updated from revA to revB.

datasheet revA
datasheet revB
Background:
As a ROSC = 0ohm circuit design, it is used in our products.
Recently, defective products have occurred in the part of using TPS5405, and several cases have been solved after replacing the IC.
Therefore, it is found that the item with ROSC = 0ohm is deleted when rereading the latest datasheet,
I think this item is deleted for some reason, but if the constant setting of ROSC = 0ohm is not recommended,
so I want to know the status.
For that reason, please let me know if I need to revise the design.
Thanks for your confirmation in advance.
Regards,
