随着信息高速发展，光模块在通讯领域发挥着越来越广，使用范围越来越宽，更新迭代也越来越快。据此，本文推荐在设计中采用使用圣邦微（SGMICRO）推出的同步降压DCDC SGM6012，封装小，输出电流大，效率高。

下图为光模块设计中SGM6012所在模块的框图：

如下为圣邦微SGM6012的特点：

1、 TSOT-23-5封装，封装小，占用PCB设计更小，减小产品设计大小；

2、输入电压：2.5~5.5V，输入电压范围宽，满足多种电压设计；

3、效率：95%，转化效率高，减少系统损耗；

4、 1.6MHz开关频率，开关频率高，外部电感较小；

综上所述，圣邦微推出的同步降压DCDC SGM6012，具备小封装、宽电压、高效率等特点，满足光模块中部分电源需求。
