LM5143: Do you have any current sharing waveform avaiable for the reference design SNVA870A?

Part Number: LM5143

Hi Team,

I am checking the performance of LM5143A-Q1's current sharing. However, there is no info available in any of your literatures. So here am i to ask if you have any waveform and any design experience about LM5143A's current sharing in single out interleaved operation? Thanks

Albert,

See reference designs:

I didnt see any current sharing waveforms specifically, however the switching waveforms along with the thermal images and inductor temperatures being close together imply well-balanced phase currents.

Hope this helps,
