Efficient Power Conversion Corporation (EPC) announced the EPC2040 power transistor, an extremely small, fast switching gallium nitride power transistor that enables superior resolution, faster response time, and greater accuracy for high speed end-use applications. High stability of the threshold over temperature ensures the high stability as the laser heats up.
For example, this product is ideal for pulsed laser drivers used in LiDAR technology, the technology at the heart of autonomous vehicle guidance systems and augmented reality platforms. The end result of the EPC2040’s superior performance is increased accuracy and higher resolution in these systems.
The low temperature coefficient of the gate threshold of the EPC2040 eGaN FET contributes to enhanced end-use system performance. This feature gives consistent results, thus enabling lower laser diode power and high quality system operation over its entire operating temperature range.
Benefits of using eGaN FETs in augmented reality systems include lower laser diode heat resulting from narrower pulse widths, high efficiency due to lower laser diode driver heat, more compact systems because of the small eGaN FET footprint, and consistent operation because of the EPC2040 is stable with temperature.
Steve Colino, Vice President Strategic Technical Sales, points out that, “The EPC2040 was designed specifically for applications requiring high frequency, narrow pulse width capabilities. These are the requirements that are critical to improving resolution in LiDAR, the technology at the heart of collision avoidance and guidance systems in autonomous vehicles.”
