12V/5A Output From 4V-38V Automotive Input Supply

LTC3789 是一款高性能、降压-升压型开关稳压控制器,可以在输入电压高于、低于或等于输出电压的情况下运作。该器件运用了恒定频率、电流模式架构,故可提供一个高达 600kHz 的可锁相频率,而一个输出电流反馈环路则提供了对电池充电的支持。凭借 4V 至 38V (最大值为 40V) 的宽输入和输出范围以及工作区之间的无缝和低噪声转换,LTC3789 成为了汽车、电信和电池供电型系统的理想选择。

工具及仿真模型

LTspice

LTspice® is a powerful, fast and free simulation software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits.

To launch ready-to-run LTspice demonstration circuits for this part:

Step 1: Download and install LTspice on your computer.

Step 2: Click on the link in the section below to download a demonstration circuit.

Step 3: If LTspice does not automatically open after clicking the link below, you can instead run the simulation by right clicking on the link and selecting “Save Target As.” After saving the file to your computer, start LTspice and open the demonstration circuit by selecting ‘Open’ from the ‘File’ menu.
