RT8581
Description
The RT8581 is a boost converter that integrates built-in power transistors, synchronous rectification, and low supply current to provide a compact solution for systems using advanced Li-Ion batteries. The RT8581 is capable of supplying significant energy when the battery voltage falls below the voltage required by system power ICs.
