DA9030: Power management for communications and applications processors, including Marvell

Dialog Semiconductor’s DA9030 is a highly integrated power management IC (PMIC)designed to minimize power consumption in entry-level, mid-range and premium smartphones as well as personal digital assistants (PDAs) and communicators with highly sophisticated multimedia and internet capabilities. It is targeted at cell phones incorporating radios for W-CDMA, quad-band GSM, Wi-Fi (802.11b wireless LAN) and Bluetooth. The DA9030 manages the complete power management requirements of both the communication and application processors, such as Marvell’s PXA9xx and PXA27x families.

Providing a complete system power management solution the DA9030 integrates Dialog’s patented Smart Mirror linear regulators which exhibit very high power supply rejection whilst operating at very low quiescent current. Complementing the linear regulators are two switching buck converters providing high current, low voltage supplies. The converters are optimized for high efficiency (greater than 92%) and feature integrated low impedance FETs. When not supporting dual processor systems the second buck converter can be configured to support external low voltage memory.

The DA9030 includes a fully programmable multimode battery charger. The charger uses dual loop monitoring and control for rapid and safe operation, providing automatic charger detection and battery pack temperature monitoring. Other functions integrated include programmable white LED, general purpose LED, 500 milliwatt hands free speaker driver and vibrator driver, minimizing the need for external components.

The DA9030 is offered with a number of variants to support different system configurations. Alternative buck output voltage, battery charger threshold and start up voltage are available.
