Abstract:
A power converter includes at least a first phase including a high-side MOSFET transistor (HSA) and a low-side (LS) MOSFET transistor (LSA) driving a first output inductor. The first phase further includes an active gate drive assist circuit including first MOSFET switch (first switch) and second MOSFET switch (second switch) positioned in series between a source of HSA and a drain of LSA. A capacitor (CS) is between the source of HSA and drain of LSA. A bootstrap capacitor (CA) having a reference terminal is connected to a node between the first switch and the second switch.
