General Description

The RT4823 integrates built-in power transistors, synchronous rectification, and low supply current to provide a compact solution for systems using advanced Li-Ion battery chemistries.

The RT4823 is capable of supplying significant energy when the battery voltage is lower than the required voltage for system power ICs.

The RT4823 is a boost regulator designed to provide a minimum output voltage from a single-cell Li-Ion battery, even when the battery voltage is below system minimum.

Key Features
