DA9034
Key Features
- Dedicated support for Marvell® PXA3xx solutions Audio and Power subsystem for advanced applications processors The DA9034 is a complete and highly integrated analog baseband solution. Designed to support advanced applications processors, the DA9034 provides all power management and audio functions for advanced handset/PDA/PNA designs. Connecting directly to the battery the DA9034 provides stable, low noise supplies for all core voltage domains, with additional regulators for supplying peripheral ICs. All supplies are fed using high performance low dropout (LDO) voltage regulators using Dialog’s patented Smart Mirror ™ technology (patent pending) offering very low quiescent current consumption and high power supply rejection performance. Smart Mirror ™ regulators remove the need for a low power mode, simplifying power control. Two high efficiency DC-DC buck converters provide high current, low voltage supplies to the processor core and memory. The main converter features Dynamic Voltage Management (DVM) with programmable voltage and slew rate control. The DA9034 also provides a range of other functions including battery charger, touchscreen interface and programmable LED drivers to enable a complete system to be realized without requiring additional external IC’s. Complementing the power management function is a full audio subsystem containing a voice codec and HiFi stereo DAC. The codec’s are supported by a range of analog interfaces including loudspeaker and headphone drivers. Ancillary functions include programmable white LED and general purpose LED drivers, vibrator driver and support for USB interfacing (VBUS generation monitoring and control). Also included is full time battery supervision with over/under voltage, over current and thermal protection.
