FAN48630BUC3AJX

Fairchild FAN4863x TinyBoost� regulator 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 FAN48630 is a boost regulator designed to provide a minimum output voltage (VOUT(MIN)) from a single-cell Li-Ion battery, even when the battery voltage is below system minimum. Quiescent current in Shutdown Mode is less than 3A, which maximizes battery life. The regulator transitions smoothly between Bypass and normal Boost Mode. The device can be forced into Bypass Mode to reduce quiescent current.
