Practical Layout Techniques to Fully Extract the Benefits of eGaN FETs

Practical Layout Techniques to Fully Extract the Benefits of eGaN FETs

The trend for electronics is to continually push towards miniaturization while increasing performance. With silicon MOSFET technology fast approaching its theoretical limit, enhancement mode gallium nitride (eGaN®) FETs from EPC have emerged to offer a step change improvement in power FET switching performance, enabling next generation power density possibilities by decreasing size and boosting efficiency. This article will explore the recommended layout techniques required to fully extract the benefits of EPC’s eGaN FETs.

eGaN FET-Silicon Power Shoot-Out Volume 13, Part 1: Impact of Parasitics on Performance

The ability of enhancement mode gallium nitride based power devices, such as the eGaN® FET, to achieve higher efficiencies and higher switching frequencies than possible with silicon MOSFETs has been demonstrated for a variety of applications. With improvements in switching figure of merit provided by eGaN FETs, the packaging and PCB layout parasitics are critical to high performance. This first part of this article will study the effect of parasitic inductance on performance for eGaN FET and MOSFET based point of load (POL) buck converters operating at a switching frequency of 1 MHz, an input voltage of 12 V, an output voltage of 1.2 V, and an output current up to 20 A.
