Overview
RT4805B 2.
5MHz, Synchronous Boost Regulator with Bypass Mode General Description The RT4805B 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 compact solution for systems using advanced Li-Ion battery chemistries.
The RT4805B 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.
In boost mode, output voltage regulation is guaranteed to a maximum load curr...
