How FIT is GaN?

What this episode covers

Doug Bailey, VP of Marketing and Applications Engineering at Power Integrations, explains how the company validated Gallium Nitride (GaN) technology for high-reliability applications by first deploying it in the high-volume charger market to gather real-world failure data. He details Power Integrations' decision to use depletion mode devices with cascode configurations to achieve lower costs and higher efficiency compared to enhancement mode alternatives, while also discussing the technical necessity of 750V and 900V variants for appliances and automotive systems. Bailey argues that GaN’s low parasitics allow for simpler power supply topologies, such as flyback converters at higher power levels, and predicts that GaN will eventually replace silicon in many applications due to its favorable energy processing costs.
