LM5170: LM5170

Part Number: LM5170


Tool/software:

Hi,

I am calculating the MOSFET loss for lm5170-Q1 2 phase bidirectional converter, I have a clarification for MOSFET loss calculation for Boost and Buck mode based on the SLVAEQ9 reference document,

In the below equation whether we have to consider the Io is output current or the switching current ie Drain current.

Drain current is calculated by refereeing the document basic buck calculation doc, 

For Buck,

For Boost,

Please help me to clarify same.

Regards
