FAN48630J
2.5MHz,1500mA,SynchronousTinyBoostRegulatorwithBypassMode
The FAN48630J 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 FAN48630J 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 1500 mA.
Quiescent current in Shutdown Mode is less than 3 µA, 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 FAN48630J is available in a 16-bump, 0.4 mm pitch, Wafer-Level Chip-Scale Package
(WLCSP).
