RT4803B Datasheet (Richtek) - 2.5MHz Synchronous Boost Regulator

RT4803B, 2.5MHz Synchronous Boost Regulator

The RT4803B 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
