Hi,
My customer has question about TPS53014.
Could you tell us about question?
[Question]
My customer has question about Inductor current value on PMP8670.
She calculate TPS53014's current limit value on PMP8670. It is below.
R10=6.81k (Vtrip=0.05)
Low Side FET Rds(on)=2.3mohm(typ), 3mohm(max) at Ta=25deg
Valley current limit value = Vtrip / Low Side FET Rds(on)
= 16.7A(typ), 21.7A(max) at Ta=25deg
But Inductor(L1) current value is 20.5A. She think there is danger of saturation.
Could you explain how to choice inductor current value?
Best Regards,
