<!-- Paste General 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.The RT8581 is designed to provide a minimum output voltage from a single-cell Li-Ion battery, even when the battery voltage is below the system’s minimum voltage requirement. The RT8581 is available in the WQFN-11L 2.5x2 (FC) package. The recommended junction temperature range spans from -40°C to 125°C, while the ambient temperature range extends from -40°C to 85°C.
