As datasheet mentioned, LT8550 is in tandem with any buck DC/DC converter to increase the load current capability.
We do like to combine LTC7803+LT8550 5 Phases application to achieve 19V->12V/85A which is around 1kW.
If it is a suitable design ?
Is there any limit for the "Primary Controller" to cycle-by-cycle duplicate the operation ?
Please kindly help with it.
Thanks a lot !!
