APPLICATIONS
GENERAL DESCRIPTION
DA9131-A integrates two single-phase buck converters, each phase requiring a small external 0.22 µH inductor. With remote sensing, the DA9131-A 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 DA9131-A in the same application. DA9131-A has integrated over-temperature and over-current protection for increased system reliability, without the need for external sensing components.
