WebBuck-Boost Converters (dc-dc) A buck-boost converter (dc-dc) is shown in Fig. Only a switch is shown, for which a device belonging to transistor family is generally used. Also, a diode is used in series with the load. The connection of the diode may be noted, as compared with its connection in a boost converter (Fig.a). WebThe GaN-FET-based multilevel buck topology can be used for designing an ultra-thin and highly efficient DC-to-DC converter. A 48 V to 20 V, 250 W three-level buck converter built using eGaN FETs achieved a peak efficiency of 97.8% and an overall thickness of only 5 mm. The multilevel topology allows the use of a thin inductor with derrick white poster
