DA9141 High-Performance, 25 A/40 A Peak, DC-DC Converter General Description The DA9141 is a high efficiency, 25 A continuous and 40 A peak, four-phase, DC-DC stepdown converter (buck). It is also available as fully AEC-Q100 qualified. With remote sensing, the DA9141 improves output voltage regulation at the point of load. Fully integrated switching FETs means no external FETs or Schottky diodes are needed. A programmable soft startup 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.
