Pulsed-Load Synchronous Regulator with Bypass Mode for GSM PA Supply, TINYBOOST), 2.5 MHz, 2.0 A FAN48632 Description The FAN48632 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 FAN48632 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. In boost mode, output voltage regulation is guaranteed to a maximum load current of 1.5 A continuous and 2.0 A pulsed.
