Description
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.
Applications
Smart Phones, Feature Phones
Tablets, Portable Gaming Devices
GPS, Active Speakers
