摘要：
This paper presents two buck converters switching at 50 MHz and based on Gallium Nitride dice. The first converter features a diode designed for power applications and demonstrates 87.9% peak efficiency. The diode mounted on the second one is aimed at higher-frequency operation and brings this value up above 91% in the same operating conditions. Loss contributions are evaluated, showing the influence of the diode alone on the efficiency of such converters.
