RT4803A
RT4803A is Synchronous Boost Regulator manufactured by Richtek.
2.5MHz, Synchronous Boost Regulator
General Description
The RT4803A 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 bining built-in power transistors, synchronous rectification, and low supply current; this IC provides a pact solution for systems using advanced Li-Ion battery chemistries.
The RT4803A 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 current of 2000mA....
