伴随着目前电子行业的飞速发展，为了更好提扫地机器人稳定性，现在不少大体量公司选用圣邦微DCDC控制器 SGM6601用于扫地机系统的开发设计。本文将阐述关于SGM6601用于扫地机系统的开发经验分享，希望对大家能有所帮助。

首先，SGM6601原理图如下所示，从原理图我们可以知道：SGM6601输入电压范围1.8V--6V，输出升压高达38V,几乎可以满足市面上所有的小电池应用，SGM6601内部有400毫安开关电流限制，20μA的静态电流，大大提高了系统级别稳健性。

由于DCDC电路结构都比较简单单一，工程师一般都是拿到手就用，但是还是有一些细节末支需要设计研发时留意，

1、SGM6601内部有400毫安开关电流限制，并不是说SGM6601能输出400毫安电流。

2、感量计算公式如下：

3、SGM6601为DFN封装，底部有焊盘，接GND，芯片主要靠底部焊盘散热。

4、由于有底部焊盘散热，如果底部焊盘画的太大，散热条件太好，风枪拆芯片时间过长，会有一定概率吹坏IC，因此在PCB设计中要按照实际需求来。

请问升压LED驱动芯片TPS61040DDCR的数据手册中，有一个应用参考电路是把LED的阴极接到FB（如图），其中的对地电阻RS是起到检流/限流作用吗？那这个电阻取值是怎么计算的呢，手册中没看到有相关的解释，而且这个电路是否能够做到恒流驱动？

黄工您好，我们目前没有代理TPS61040DDCR，推荐您评估台舟电子的LED横流驱动芯片TP7820S6，数据手册链接：https://www.sekorm.com/doc/2527700.html 或者圣邦微的LED驱动芯片SGM6601，PTP替代，数据手册链接：https://www.sekorm.com/doc/196451.html
