Description
The AT73C212 provides a power management solution for integration of multimedia
features in mid-level mobile phone handsets. These features may include a camera
module (CMOS or CCD), audio generators for a polyphonic or MP3 ringer, a co-processor for JPEG encoding and an external memory module.
The AT73C212 contains six power supplies: five linear voltage regulators providing
output voltage from 1.8V to 2.8V and output current from 10 mA to 130 mA and a DC DC converter supplying 300 mA from 1.9V or 2.5V.
