1. Need to design a buck-boost. Inout 10V-30V, output 12.36V/1.55A. Saw this circuit from XLSEMI pic attached using XL6019.

2. It has weird implentation of L1,CDC,L2 & D1 as in pic.
But wiki shows different implentation, no where Isaw two indcutors used, D1 is also in reverse diection,?

3. Is it ok to use as given by XLSEMI? Cannot understand its operation
