Fundamental microelectronics innovations such as high voltage GaN and developments in power converter topology and implementation, are key weapons in the world’s push for decarbonization and energy sustainability. Together, they deliver excellent efficiency, eliminate many parts from system bills of materials, minimize power sub-system volume, heatsinking requirements and enclosure size and weight. The environmental benefits of smaller physical size, reduced complexity and minimal heat dissipation ripple through the supply and use chain from primary mineral sourcing to shipping costs to end user electricity bills. Even so, when sustainability is considered at a business level, there’s often a question of whether or not you can run a growth-oriented and profitable enterprise while providing products with an environmental focus. This presentation discusses the critical role of efficiency in sustainability and how our innovations allow us to do good for the environment while doing well as a business.
