DA9132-A是一种高效率，汽车等级，双通道，步进DC-DC（降压）转换器，每个通道的集成开关FET提供3 A.该装置可以以高于90％的效率水平运行，降低了在广泛的汽车系统中为高电流轨道提供电源的热设计挑战，例如导航系统，信息娱乐，远程处理，先进的驾驶员辅助系统（ADAS）或任何汽车高性能处理系统需要高效，高电流，电力输送。
The DA9132-A 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 DA9132-A 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 DA9132-A 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 Industrial/commercial grade version is also available (DA9132）。

Benefits
高效降压转换器提供出色的热性能
Fully integrated switching FET’s means no external FETs or Schottky diodes are required
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.
Dynamic voltage control (DVC) enables adaptive adjustment of the device output voltage depending on the load. This increases efficiency when the downstream circuitry enters low power or idle mode, resulting in power savings.
可配置的GPIOS支持一系列功能，包括I2C，DVC和电源良好指示灯。
优化的BOM成本和占用空间：每个输出需要一个非常小的电感器和电容器提供零件和成本节约
