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. The device is available in two compact, space-saving package options: 32-ball BGA or 32-pin QFN.
