The FAN48630 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. Output voltage regulation is guaranteed to a maximum load current of 1500mA. Quiescent current in Shutdown Mode is less than 3µA, 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.The FAN48630 is available in a 16-bump, 0.4mm pitch, Wafer-Level Chip-Scale Package (WLCSP).
