That probably won’t change the efficiency by much, but it might reduce the cost if you can use a lower voltage chip and a smaller inductor. But I am designing other product which requires Dual outputs. I didn’t get any useful information from your answer. You haven’t reported power efficiency vs design goal, but I suspect losses are higher than estimates and sensitivity to Pout with each component loss parameter variations.

Product is in design stage Target: The problems with regulation and stability using a perfectly good regulator for a nonlinear load do not follow the rule of BOde plot phase marginnor precise regulation and hence much higher gain error sensitivity to all parameters even with infinite gain in the 2.

As you know, the transfer function is nonlinear for any diode and with and array of 3P5S is offset by that Zener like threshold and amplified by the incremental slope of diode ESR such that for each colourthe string VoltageVs, is the samebut each string will equate a different current transfer function as follows.
