FAN48623UC50GX

FAN48623UC50GX is a 2500mA, synchronous TinyBoost® regulator with bypass mode in a 16 pin WLCSP package. The FAN48623 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. It 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. The output voltage regulation is guaranteed up to a maximum load current of 2500mA. The regulator transitions smoothly between Bypass and normal Boost Mode. Typical applications include boost for low-voltage li-ion batteries, brownout prevention, system PMIC LDOs supplies, and 2G/3G/4G RF PA supplies and smart phones, tablets, portable device.
