UCC28730-Q1: [ELENTEC] Request for review on whether or not circuit configuration is possible

Hi MJ,

Thank you for the query on UCC28730.

There needs to be a lot of changes. The PMP design is only 4.8W and your design is 72W. 

The inductor (L1), diode (D1) D2 and D3 should be ok I think, the Vs pin resistors (R1 and R2), Q1 should probably be ok, the current sense resistor R6 and output capacitors needs to be redesigned. There are not much design calculators for UCC28730 configured for non isolated buck. But the following app note should be a good place to start with for the choice of components.
