DA9024 DA9024 Quad 1.2A Buck PMIC with Audio Drivers The DA9024 is a quad buck 1.2A per channel PMIC with 20 linear regulators, an integrated, class-G, true-ground capless headphone driver, and a class D speaker driver, enabling supply domain flexibility to support associated peripherals and user interface functions. Controlled by a programmable digital power manager the user-programmable switched and linear regulators have configurable startup sequences, levels and timing. For optimal processor energyper-task performance dynamic voltage scaling is available on four supply domains. All linear regulators use Dialog’s Smart Mirror™ 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. All converters use a high switching frequency (2MHz) allowing the use of small 2.2uH external inductors. A backup battery charger and an ultra-low power real-time-clock (RTC) are also implemented on the IC. The DA9024 contains a class-G true-ground “capless “headphone driver and a Class D Speaker driver, with Power-Limiter, along with two differential or four single ended input channels with analog routing/mixing. The DA9024 is controlled by a bidirectional I2C interface and can operate in Standard Mode (up to 400kHz) and High Speed Mode (up to 1.7Mhz) allowing for a highly flexible configuration of end applications. www.dialog-semiconductor.com Features Applications ► Smartphone Handsets ► 4 x high efficiency programmable buck ► Consumer Infotainment Devices converters with DVC and pin controlled states ► Embedded products ► 20 programmable LDO regulators ► 4 input Audio mixer with Capless 45mW Class G headphone and 1.5W (8Ohms) Class D speaker drivers ► High speed I2C interface ► Back up battery charger ► Ultra-low power (<1 µA ) 32kHz Real Time Clock with alarm wakeup capability ► Temperature / voltage supervision ► Package : 108bump WL-CSP 3.6mm x 4.8mm – 0.4mm pitch Package Outline Drawing www.dialog-semiconductor.com 400mA LDO 12 LDO 4 LDO 13 LDO 5 LDO 14 LDO 6 LDO 15 LDO 7 LDO 16 LDO 8 LDO 17 LDO 9 LDO 18 General Purpose 10-bit ADC 300mA LDO 11 Buck 1 150mA 1200mA 150mA Buck 2 150mA 1200mA 150mA Buck 3 150mA 1200mA 150mA LDO 3 150mA LDO 10 Buck 4 150mA LDO 2 Backup Battery Charger 150mA LDO 1 1200mA 150mA 6mA Block Diagram DA9024 400mA 150mA 150mA 150mA 150mA 150mA 150mA LDO 19 150mA LDO 20 LDO Audio Multiplexed I/O Extender 50mA Real Time Clock Power Manager L Headphone Class G Audio IN 1 R Headphone Class G Mixer & Mux Audio IN 2 Class D Out 2 x I2S 1 cell Li ion Dialog Semiconductor Worldwide Sales Offices - www.dialog-semiconductor.com United Kingdom Phone: +44 1793 757700 The Netherlands Phone: +31 73 640 88 22 Japan Phone: +81 3 5425 4567 Singapore Phone: +65 648 499 29 Germany Phone: +49 7021 805-0 North America Phone: +1 408 845 8500 Taiwan Phone: +886 281 786 222 Hong Kong Phone: +852 3769 5200 This publication provides outline information only, which unless agreed by Dialog Semiconductor may not be used, applied or reproduced for any purpose, or be regarded as a representation relating to products.
