Hi,
My customer has questions.
Q1.
Datasheet P15 of TPS 54427,
From the Power Supply Recommendations section,
Vout ÷ 0.65 or more is required.
further,
The voltage drop due to Rds is added to Vout ÷ 0.65,
I think VIN is necessary.
VIN> Vout / 0.65 + Rds * Iout
When VIN is less than Vo / 0.65 + Rds * Iout,
What kind of problems do you encounter?
Q2.
I checked the data sheet of TPS54627, TPS54227 which seems to be a different output voltage product.
In TPS54227,
There is a section on Power Supply Recommendations.
There is no description of Vo / 0.65.
In TPS54627,
There is not even a section of Power Supply Recommendations.
TPS54427 only Please tell us why Vo / 0.65 is recommended and required.
Best regards,
-Watanabe
