Does SM72445 use ZVSCS?

Other Parts Discussed in Thread: SM72445

I am carrying out a project in which I have to develop a power optimizer for application in photovoltaics. I have purchased some SM72445 MPPT controllers and the evaluation board to test how it works. I tested the evaluation board and another optimizer based on a SM72445 and the efficiency was really high. Could you let me know please if this MPPT controller uses Zero Voltage-Zero Current Switching techniques? This information is necessary in order to document the project.

Thanks a lot for your time.

The datasheet does not mention Zero Voltage-Zero Current Switching. The topology looks like a traditional 4 switch buck or buck boost, with proprietary algorithm to handle the transitions between those two topologies.

I read all data sheets about the product and I know perfectly the hardware design of the demo board. My question is mainly for Texas Instrument's engineers or people with high experience using this microcontroler.

So far as I can tell, those engineers do not participate in these forums. I post here frequently and will try to answer questions outside my particular expertise when I think there is a low probability of another answer. We can see if anyone else responds.
