AR/VR glasses

The ‘reality‘ of augmented reality (AR) or virtual reality (VR) glasses is really the need for efficient devices. Our product portfolio not only provides this capability, but also includes low-power and space-saving packaging.”

Design considerations

There is a balance to be struck between ultra-long battery life and always-on functionality-energy efficiency is very important
Low power consumption is essential for these small wearable devices
Requires very small package or wafer-level chip occupation area
For more energy-efficient wired charging, you can use two back-to-back mosfets instead of built-in Schottky diode.”
