Power Integrations is one of the primary suppliers of GaN based power ICs, specialising in very highly integrated solutions. It has announced the expansion of its InnoSwitch4-CZ family to meet the latest USB PD 3.1 specification, allowing adapters to reach power ratings up to 220W.
So far, highly integrated solutions have been used in designs of lower power solutions (65W and below) in most use cases. This announcement is likely to accelerate the transition to higher power designs, made possible by the higher efficiencies achievable by GaN based solutions. More on the opportunity for different types of GaN components as well as forecasts for the GaN power adapter & charger market can be found in SAR Insight & Consulting’s upcoming GaN Power Adapters & Chargers Report, being released as part of its wider USB Power & Charging service.
