Fairchild FAN48623 synchronous TinyBoost regulator is designed to enable the system to take advantage of new battery chemistry.
When the battery voltage is lower than the voltage required by the system power IC, these devices can provide a lot of energy. By combining built-in power transistors, synchronous rectification and low supply current, the voltage regulator IC provides a compact solution for systems using advanced lithium-ion battery chemistry.
The device is designed to provide a minimum output voltage from a single-cell lithium-ion battery, even if the battery voltage is below the system minimum. Ensure that the output voltage is regulated up to a maximum load current of 2500mA. The regulator transitions smoothly between bypass and normal boost mode. The device can also be forced into bypass mode to reduce quiescent current. Applications include enhanced low-voltage lithium batteries, power-down protection, system PMIC LDO power supplies and 2G / 3G / 4G RF PA power supplies, smartphones, tablets, and other portable devices. device.
