TPS53355 - Vtrip and Rtrip value

Guru 20090 points
Other Parts Discussed in Thread: TPS53355

Hello TI PWR Team,

Could you please let me know the accuracy of the current limit of TPS53355 ?

In the customer , the output current and Rtrip combinations are the following.
If there is problem please let me know. From equation (10) of the datasheet, I can't get the worst case of Rds(on).

a ) Iout=2A,   Rtrip = 18.9kohm
b)  Iout=10.5A, Rtrip = 54kohm
c)  Iout=1.1A , Rtrip = 7.2kohm
d) Iout=5.7A , Rtrip = 35.6kohm
e) Iout=2A, Rtrip=14.9kohm

Also, I asked other question to the folloing post about Vtrip range. I'm looking forward to the reply for that too.
