DA9130 High-Performance, 10 A, Dual-Phase DC-DC Converter General Description
DA9130 is a power management unit (PMU) suitable for supplying CPUs, GPUs, DDR memory rails in switches and routers, smart metering, industrial automation, wireless applications, consumer products, and SoC/FPGA high performance processing systems requiring efficient, high current, power delivery. DA9130 operates as a single-channel dual-phase buck converter, each phase requiring a small external 0.10 µH inductor. It is capable of delivering up to 10 A output current at a 0.3 V to 1.9 V output voltage range. The 2.5 V to 5.5 V input voltage range is suitable for a wide variety of low- voltage systems. With remote sensing, the DA9130 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 DA9130 in the same application. DA9130 has integrated over-temperature and over-current protection for increased system reliability, without the need for external sensing components.
Key Features
■ 2.5 V to 5.5 V input voltage ■ Key safety features ■ 0.3 V to 1.9 V output voltage □ Output under-voltage and over-voltage ■ 4 MHz nominal switching frequency protection ■ □ ±1 % accuracy (static) Input under-voltage protection ■ □ ±5 % accuracy (dynamic) 2-step over-temperature protection ■ ■ I2C-compatible interface (FM+) -40 °C to +85 ºC ambient temperature range ■ Programmable GPIOs ■ 24-pin FCQFN package (nom. 3.3 mm x 4.8 ■ Programmable soft-start mm) ■ Voltage, current, and temperature □ Wettable flanks supervision
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. ■ Configurable GPIOs support a range of features including I2C, DVC and Power-Good indicator.
