APPLICATIONS
GENERAL DESCRIPTION
DA9130 operates as a single-channel dual-phase buck converter, each phase requiring a small external 0.22 µH inductor. 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 (I2Ccompatible) 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.
