1 / 56 page  DA9131 High-Performance, Dual-Channel DC-DC Converter for Mobile and Portable Applications Datasheet Revision 2.0 11-Aug-2021 CFR0011-120-00 1 of 56 © 2021 Dialog Semiconductor General Description DA9131 is a power management IC (PMIC) suitable for supplying CPUs, GPUs, DDR memory rails in single in-line pin package (SIPP) modules, mobile, portable and consumer applications. DA9131 integrates two single-phase buck converters, each phase requiring a small external 0.22 µH inductor. Each buck is capable of delivering up to 5 A output current at a 0.3 V to 1.9 V output voltage range. The 2.8 V to 5.5 V input voltage range is suitable for a wide variety of low-voltage systems. With remote sensing, the DA9131 guarantees the highest accuracy and supports multiple PCB routing scenarios without loss of performance. The pass devices are fully integrated, so no external FETs or Schottky diodes are needed. A programmable soft start-up can be enabled, which limits the inrush current from the input node and secures a slope-controlled rail activation. The dynamic voltage control (DVC) supports adaptive adjustment of the supply voltage dependent on the processor load, via either a direct register write using the communication interface (I2C- compatible) or with a programmable input pin. A configurable GPI allows multiple I2C address selection for multiple instances of DA9131 in the same application. DA9131 has integrated over-temperature and over-current protection for increased system reliability, without the need for external sensing components. Key Features ■ 2.8 V to 5.5 V input voltage ■ 0.3 V to 1.9 V output voltage ■ 4 MHz nominal switching frequency ■ ±1 % accuracy (static) ■ ±5 % accuracy (dynamic) ■ I2C-compatible interface (FM+) ■ Programmable GPIOs ■ Programmable soft-start ■ Voltage, current, and temperature supervision ■ Key safety features □ Output under-voltage and over-voltage protection □ Input under-voltage protection □ 2-step over-temperature protection ■ -40 °C to +105 ºC ambient temperature range ■ AEC-Q100 Grade 2 qualified version also available for Automotive applications (DA9131-A) ■ 24-pin FCQFN package (nom. 3.3 mm x 4.8 mm) □ Wettable flanks Benefits ■ High Efficiency buck converters deliver outstanding thermal performance ■ Fully integrated switching FET’s means no external FETs or Schottky diodes are required ■ Remote sensing guarantees the highest accuracy and supports multiple PCB routing scenarios without loss of performance. ■ Fully programmable soft-start limits the inrush current from the input to give a slope-controlled output voltage. ■ Dynamic voltage control (DVC) enables adaptive adjustment of the device output voltage depending on the load. This increases efficiency when the downstream circuitry enters low power or idle mode, resulting in power savings. |
