【应用】国产串联型基准电源SGM4027-2.5XN3LG/TR助力400G硅光模块产品设计

时间： 2022-09-04 来源：世强

技术问答

某客户在设计一款400G硅光模块QSFP-112DR4产品设计时，主控MCU选用的一款国产MCU，需要一款串联型基准电源来给DAC做电压参考，客户希望用一款小封装、高精度、低温飘的国产基准源，要求输出电压2.5V，工作电流1mA以上。综合客户需求，本文推荐国产圣邦微（SGMICRO）SGM4027-2.5XN3LG/TR，满足客户的设计需求。

SGM4027-2.5XN3LG/TR的电路搭配设计如下图所示：

SGM4027-2.5XN3LG/TR的产品优势有以下几点：

1、 SGM4027支持多电压固定输出，光模块的供电电压值一般为2.5V、3.3V，可以满足客户的多种供电电压需求

2、输出电流最高可达10mA，电路中这个部分需要电流不大，此芯片完全满足应用。

3、 SGM4027-2.5XN3LG/T的初始精度为±0.1%，精度非常高，可以满足客户对产品的高精度要求

4、 SGM4027-2.5XN3LG/T常温下温漂为10ppm/℃，最大温漂35ppm/℃，在工作温度内其输出的电压变化很小，所以芯片的输出电压会十分稳定。

5、 SGM4027-2.5XN3LG/T封装为SOT-23小封装，光模块的布板面积很紧张，小封装产品满足客户的设计需求。

另外，世强作为圣邦微的优秀代理商可以提供及时的技术服务与稳定的供货支持。
