| GaN Power Behind Mild Hybrid Vehicle Electrification - November 2022 |
November, 07 2022 |
| The hybrid vehicle market has more than doubled from 2017 from 2.0 to 5.1 percent [1] and by 2025, one of every 10 vehicles sold worldwide is projected to be a 48 V mild hybrid. 48 V systems boost fuel efficiency, deliver four times the power without increasing engine size, and reduce carbon-dioxide emissions without
increasing system costs. |

| Is the 12V Lead-Acid Battery Dead? - Nov 21 |
October, 25 2021 |
| Yes, the 12 V lead-acid car battery is dead. Europe has decreed that no new cars will have lead-acid batteries after 2030, creating a considerable challenge for OEMs to find alternative solutions. While this may seem like a daunting task, it also presents a tremendous opportunity to eliminate the environmentally toxic battery while also reducing weight in a vehicle and improving overall efficiency.. |

| GaN Raises Electric Vehicle Powertrain Performance - April/May 2021 |
April, 22 2021 |
| In recent years, the number of electric vehicles (EVs) have multiplied on our global roads. Industry analysts expect that 56 million new EVs will be sold in 2040. The electricity consumption that accompanies this growth will rise to 1,800 TWh, representing 5% of global power according to Bloomberg NEF’s Electric Vehicle
Outlook. A smart, smaller, lighter-weight powertrain is a key area in creating changes for the EV industry. |
