RT4822 Datasheet (Richtek) - Wide Input and Ultra-Low Quiescent Current Boost Converter

RT4822, Wide Input and Ultra-Low Quiescent Current Boost Converter

The RT4822 allows systems to take advantage of new battery chemistries that can supply significant energy when the battery voltage is lower than the required voltage for system power ICs.

By combining built-in power transistors, synchronous rectification, and low supply current, this IC provides a c
