A four-switch buck-boost converter benefits from synchronous rectification ... The forward-voltage drop of a typical Schottky diode is around 0.6 V, and the diode conduction loss could be significant ...

Figure 3 presents a circuit with an LT8350S buck-boost switching regulator. This device can carry up to 6-A switch current and has an input voltage range of 3 to 40 V. To reduce the generated EMI ...

This is the third time that Cheng’s team has published their work in ISSCC, entitled "A 98.6%-Peak-Efficiency 1.47A/mm 2 Current-Density Buck-Boost Converter with Always Reduced Conduction Loss".
