TPS54020: Request a cross check to see if it is possible to exceed the limit of TPS54020

Part Number: TPS54020

Hi,

I have a question regarding TPS54020 as follows.

The Iout max value is about 7.56A.

Please check if the ripple current peak of the Inductor exceeds the limit of TPS54020 in the circuit designed below.

EQ19 and EQ21,

 

fsw =400kHZ, L=1.0uH,

Iripple = 2.29A
 Ilpeak = 7.56A + 2.29A/2 = 8.705A

SPM6530T-1R0M120 rated current is 14.1A Typical.

thanks,

TS
