【产品】满足军工应用的高性能国产LDO SGM2019，仅39uV低噪声

时间： 2019-05-07 来源：世强

技术问答

相信很对人都对标题中的“国产”两个字很意外，因为在大多数工程师意识里，国产器件不敢用，特别是对可靠性要求很高的医疗、军工、汽车等领域的应用，这都可以理解，毕竟对国产器件整体性能不如国际大牌产品，但不可否认，国产器件，还有一些好产品。SGM2019是圣邦微公司推出的一款通用型、高可靠性、高性能LDO，目前已在军工级产品中充分验证、批量应用，可放心选用。

SGM2019的典型特征如下图所示，仅为39uV的优异低噪声特性。其PSRR可达74dB，很好抑制纹波的同时，让电源的输出噪声非常低，能保证后级的负载受到的干扰也会小很多。最低0.9mV的压差输出，非常适合于二次稳压。同时增加了过温保护与过流保护，有效保护负载损坏。

图1 SGM2019的典型特征

SGM2019的应用电路非常简单，只需在输入、输出、BP端连接接地电容即可，封装为SC70-5或SOT-23-5,体积小，非常适合高密度布板稳压。为保证优秀的PSRR和快速的关断延时在电路匹配时应参考下图2列表进行电路配置，更详细资料可参考SGMicro（圣邦微） SGM2019 LDO 数据手册。

图2 SGM2019电路配置

相信你对SGM2019的性能指标有所了解了，对担心的莫过于可靠性问题。

加工一致性问题，圣邦微产品的晶圆加工方为著名企业台积电。

封装一致性问题，圣邦微的产品封装合作方为长电科技，通富微电，友尼森。

功能稳定性问题，以SGM2019为例，产品应用方已经过高温试验、低温试验、电老化试验、盐雾试验、温度冲击试验、振动试验、温度循环试验，性能稳定可靠。

还对可靠性还有什么问题吗？应该没有了，下面就是成本、供应及技术服务问题。该型号产品是大批量应用的成熟产品，极具批量成本优势，世强备有大量库存，现货支持。世强强大的技术团队和圣邦微本土原厂技术支持，可提供便捷服务，项目设计不卡壳，你不需要再犹豫，赶紧进行国产化替换。

【方案】30~80kW组串式光伏逆变器优选器件方案

描述- 该方案针对30~80kW的组串式光伏逆变器，采用多路BOOST升压电路，减少光伏电池组件最佳工作点与逆变器不匹配的情况，最大程度增加发电量。逆变侧采用T型三电平拓扑，开关频率支持16kHz（最佳频率点），效率最高可达98.54%。辅助电源采用1700V耐压SiC MOSFET，单端反激电源可直接应用在1000V母线系统。同时，在BOOST升压电路和逆变电路中均采用IGBT模块设计，集成度更高。

【方案】高性价比手持相位式激光测距仪优选器件方案

描述- 相位式激光测距仪具有重量轻、体积小、操作简单、精度高等特点，其需要多路高频率的时钟源实现多尺度测量，因此时钟的精度决定了测距仪的精度。目前市面上通常采取多路时钟或者多个振荡器实现，集成度低、价格高。本方案采用高性价比多路时钟发生器，帮助测距仪生产商在精度和价格方面提供很好的平衡，另外提供不同精度的时钟芯片，实现不同精度等级的测距仪产品设计。
