Buck Boost DC-DC analog section

The DC-DC BUCK-BOOST converter provides power to the bridge which drives the wireless charging coil;

this operation is done by using external power MOS driven by internal gate drivers. DC-DC BUCK-BOOST

(hereinafter named BB-DCDC) is based on digital controller: the digital machine drives the gate drivers and uses

low complexity analog circuits. Several different topologies can be implemented as shown by the following figures

(LS=Low-Side driver, HS=High-Side driver):
