Peregrine Semiconductor公司的全球最快速的GaN FET驅動器亮相

基於氮化鎵材料的場效應電晶體正在顛覆功率轉換市場和替代矽基MOSFET。 與MOSFET相比,更快速的氮化鎵場效應電晶體(GaN FET)可以在最細小的體積內實現更高的開關速度。 氮化鎵元件的承諾是可以大大縮減電源供應器的體積及重量。為了實現最高的潛在性能, 這些具備高性能的氮化鎵電晶體需要最優化的閘極驅動器。

Driving eGaN™ FETs Both gate and Miller capacitances are significantly lower

As enhancement mode gallium-nitride-on-silicon transistors (eGaN™) gain wider acceptance as the successor to the venerable - but aged - power MOSFET, designers have been able to improve power conversion efficiency, size, and cost. eGaN FETs, however, are based on a relatively new and immature technology with limited design infrastructure to quickly design and implement products.
