eGaN® FETs
for Ultra-High Frequency
Power Conversion
Hard switching power conversion at 10 MHz and above requires both high speed eGaN FETs and
a circuit that supports low common source inductance and power loop inductance. The ultra high
speed capabilities and improved device pinout of the EPC8000 series of gallium nitride transistors
enable this class of converters in applications such as envelope tracking and wireless power trans-
mission. These eGaN FETs can achieve switching transition speeds in the sub-nano seconds range,
and the gate drive loop and drain-source power path are designed for ultra low inductance.
42 V to 20 V, 40 W buck converter operating at 10 MHz
This family of devices is capable of greater than 10 MHz operation.
Efficiency of both 5 MHz and 10 MHz operation is shown in the figure
to the right.
With mobile communications traffic increasing by 70% in 2012 and over
10x by 2017, envelope tracking will provide a high efficiency RF solution.
The eGaN FET, with very low propagation delay, and high frequency
capability, and high efficiency is a key enabler of envelope tracking
converters which dramatically increases RF power amplifier efficiency.
Gate charge of the 40 V EPC80xx series device compared with the EPC2014 scaled to 1/10th of its active area.
