TPS65950

The TPS65950 is an integrated power-management/audio codec device for use in portable cellular phones,

portable media players, and other portable devices that derive their power from batteries based on Li-ion, Li-ion

polymer, or manganese-cobalt chemistries. The TPS65950 typically receives commands from either of the two

host controllers and provides power conversion/regulation and a complete audio codec section and class-D audio

amplifier.

In addition to generic support capabilities, the TPS65950 meets the specific power requirements of the TI

OMAPV1230, OMAP2430C, and OMAP3430 devices.
