技术问答

在5G前传应用中，25G LANWDM光模块因占用光纤资源少、系统成本低，得到运营商广泛选用。如下图1，在25G LANWDM光模块系统中，TOSA需要约100mA@4V电源供电，并且，鉴于25G LANWDM光模块自身特点，光模块要求供电芯片要具备体积小、效率高、性价比高的特点。

图1 25G LANWDM SFP28光模块电路结构框图

作为国产芯片厂商杰出代表的圣邦微电子（SGMICRO），推出了一款升压型DC/DC SGM66099，具有体积小、效率高、性价比高的特点。刚好满足25G LANWDM的需求。

图2 SGM66099典型应用电路

SGM66099输入电压0.9~5.2V，输出电压2.5~5.2V，而且输出电压为4V时，输出电流可在300mA以上，在电气规格上，完全满足25G LANWDM光模块TOSA的需求，而且，此时效率在93%以上，可以实现节省功耗的目的。

SGM66099被禁用时，同步升压架构使得SGM66099能够实现真正输出关闭功能，断开负载与输入电源连接，从而减少功率消耗。启动后，SGM66099的输入维持电压可低至0.4V，有效满足更宽的输入电压范围。

图3 SGM66099封装俯视图

最后，升压型DCDC SGM66099采用绿色WLCSP-1.22×0.83-6B封装，体积仅1.22mm×0.83mm大小，体积极极小，这对内部空间小、但器件多的25G LANWDM光模块来说，是非常有利的。

综上述，圣邦微推出的一款升压型DC/DC SGM66099，具有体积小、效率高、性价比高的特点，非常适合应用于25G LANWDM光模块上。

【应用】输入电压范围0.9~5.2V的同步升压转换器助力智能手环设计，静态电流典型值仅0.6μA

智能手环一般采用锂离子聚合物可充电电池供电，而锂离子电池的电压范围是3.0~4.2V，标称电压是3.7V，所以为了满足后级电路的供电，需要一颗DCDC转换芯片对锂电池输出的电压做升压处理，然后经LDO降压后再供给后级电路。本文介绍圣邦微SGM66099-5.0YG/TR用于智能手环的优势。
