The DA9130 is a high efficiency, 10A, dual phase, step down DC-DC (Buck) converter with integrated switching FET's. The device can operate at efficiency levels above 90%, reducing the thermal design challenges of powering high current rails in a wide range of high-performance electronic systems.

The device has an input voltage range of 2.5 V to 5.5 V and an output voltage range of 0.3 V to 1.9 V, making it suitable for a wide variety of low voltage systems. The DA9130 only requires two small 0.10 µH inductors, delivering a highly optimized BoM and footprint. Output voltages above 1.9 V are supported with an external resistor divider.

DA9130设备是对话框系列的柔性，可扩展，可靠的汽车系统和子PMICS的一部分，实现了“精确拟合”电源解决方案。它以3.3mm x 4.8mm 24针FC-QFN可湿性侧面套件提供。还提供汽车等级版本（DA9130-A）。

Benefits

  • High Efficiency buck converters deliver outstanding thermal performance
  • 完全集成的开关FET意味着不需要外部FET或肖特基二极管
  • 遥感保证最高的精度，并支持多个PCB路由方案而不会损失性能。
  • Fully programmable soft start limits the inrush current from the input to give a slope-controlled output voltage.
