Kirchheim, Germany: Power-management and audio semiconductor solutions specialist Dialog Semiconductor has announced its second generation of system-level power-management ICs, which now include an integrated class G codec. The DA9057’s five on-board dc-dc converters support 24-bit stereo audio headphone playback on a 5-mW power budget.
The DA9057 combines the industry’s most flexible power sequencer with a fully programmable filter/mixer engine to support a wide variety of ARM-based multimedia processors. The integration of a dual-input switching USB power manager/Li-ion battery charger plus five programmable dc-dc converters maximizes its power handling capability.
This architecture increases the current available to a system, enables “instant on” operation, and allows handsets to run cooler with less time spent charging. A dedicated programming graphical user interface empowers OEMs to easily optimize a system’s power sequencing requirements, even when additional functionality is added late in the design cycle.
