The FAB3103 is a mono Class-D audio amplifier with an integrated boost regulator that achieves high output audio over a power supply range of 2.5V to 5.2V.Automatic Boost Shutdown dynamically shuts down the boost regulator at low output power for greater efficiency and lower quiescent current consumption.Automatic Gain Control (AGC) monitors the battery and reduces gain as the battery voltage drops to limit maximum current consumption, extending battery runtime and preventing mobile device shutdown.
