DA9130是具有集成开关FET的高效率，10A，双相，步进DC-DC（降压）转换器。该器件可以以高于90％的效率水平运行，降低了在各种高性能电子系统中供电的高电流轨道的热设计挑战。
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.
The DA9130 device is part of the Dialog family of Flexible, Scalable, Reliable Automotive System and Sub PMICs enabling an “Exact Fit” power solution. It is available in a 3.3mm x 4.8mm 24-pin FC-QFN wettable flank package. An Automotive grade version is also available (DA9130-A.).
