RT4823N
Description
The RT4823N is a boost converter designed to provide a minimum output voltage from a single-cell Li-Ion battery, even when the battery voltage is below the system minimum. The RT4823N allows systems to take advantage of new battery chemistries that can supply significant energy even when the battery voltage is lower than the required voltage for system power ICs.
