【选型】pin to pin替换TI TPS54202的开关电源芯片SGM61230，输出电流更大，静态电流更小
某客户的扫地机器人产品中，主电源芯片使用的是TI的TPS54202，规格为28V/2A，用于4节串锂电池电源供电的一级电压处理，降压至5V后供后级电路使用。由于价格及交期的原因需要寻找一款国产的替换物料，本文给大家介绍一款圣邦微的pin to pin替换物料SGM61230，可以完美替换TPS54202。
表一 圣邦微的SGM61230与TI的TPS54202产品参数对比表
从上述的对比表中可以看出：
1. 在静态电流值方面，圣邦微的开关电源芯片SGM61230的30uA要优于TPS54202的45uA，较小的静态电流可以降低产品的整体静态电流，从而延长产品的一次性使用时间，提升产品竞争力；
2. 输出电流方面，SGM61230的3A输出电流值要高于TPS54202的2A电流值，使得该物料比TI的产品具有更加大的带载能力，使得电源在使用过程中更加安全可靠；
3. 由于该两个物料的封装及脚位完全相同，所以可以实现pin to pin替换，减小产品替换验证时间；
4. 作为国产品牌的圣邦微在价格及交期方面也比TI更加具有优势；

【应用】可输出负压的国产BUCK-BOOST电源芯片SGM660助力400G光模块，满足小型化需求
目前400G光模块的PCB空间非常紧张，器件选型时优先考虑封装能否放下。圣邦微电子的电源芯片SGM660封装为WLCSP-0.85*1.25，且外围器件只有一个电感和两个电容，电路较简单，适合小型化设计；开关限流点也有450mA/620mA可选，输出电流能力完全满足需要。
【应用】圣邦微DCDC同步降压芯片SGM61230XTN6G/TR应用于FTU，具有输入电压宽，封装体积小等特点
FTU通过互感器采集到的电压电流信号，经ADC处理后进入MCU进行分析，最后将数据通过4G/5G模组进行上传，可远程进行监控，并遥控继电器进行分合网操作。内部供电由DCDC降压芯片及LDO来完成，这里推荐SGM61230XTN6G/TR DCDC同步降压芯片。
