DA9066 System PMIC for Dual/Quad-Core Processors General Description DA9066 combines an ultra-low-power audio codec with core power management functions targeting standalone application processors and mobile phones. All linear regulators use Dialog’s SmartMirror™ dynamic biasing technique, which maintains high performance over a wide range of operating conditions and a power saving mode (Sleep mode) to minimize the quiescent current. The regulators have output voltages independently programmable via the device control interface. The buck converters do not require external Schottky diodes and offer a Sleep mode (PFM mode) for optimal efficiency at low-load currents.
