摘要

报道了一种新型的用于DC-DC功率转换的硅器件结构。在高频(1-5 MHz)下,通过同时降低栅极电荷、反向电容和栅极电阻,同时保持良好的导通电阻和关断击穿电压,实现了高效开关。在运行于1.3 MHz的同步降压变换器中实现了超过88%的功率效率。

A high-speed silicon FET for efficient DC-DC power conversion
A novel silicon device architecture for DC-DC power conversion is reported. Efficient switching at high frequencies (1-5 MHz) is achieved by simultaneously reducing gate charge, reverse capacitance, and gate resistance while still maintaining good on-state resistance and off-state breakdown voltage. Power efficiencies in excess of 88% were realized in a synchronous buck converter running at 1.3 MHz.
