随着家用电器的普及，吸尘器成为家庭中必不可少的一样家用电器，家用吸尘器内部供电主要通过DC-DC转换器或者LDO进行电压的转换，从而满足MCU、电机、传感器以及通信芯片等等各个子模块的正常工作。家用智能吸尘器常用一般选择SAMSUNG的ICR18650/2200mAh锂电池组设计，其输出电压范围12V~16.8V（4.2V/节*4节），平均输出电压14.8V（3.7V/节*4节），输出电流1.3A~5.2A。所以需要一颗高压的大电流的DC/DC电源芯片将电池电压转换为后级的相关器件供电，本文推荐圣邦微的降压DC-DC电源芯片 AAP6011A。

图1：AAP6011A关键参数

如图1所示，输入电压最高耐压40V可以满足客户的使用需求。且AAP6011A集成Mos管，使其外围应用电路比较简单，设定5V/3A输出的应用电路图如图2所示。

图2：AAP6011A 输出5V/3A电路图

电源芯片AAP6011A输出电压为0.797*(19.2KΩ+100KΩ)/19.2KΩ ≈5V，输出过流点通过CS脚的对地电阻来设定，输出电流等于78mV∕R_CS，当负载超过了芯片设定的过流点，芯片将从CV模式进入CC模式。如图3所示。

图3：CC/CV工作模式切换

电源芯片AAP6011A内部集成的高低边MOS管导通电阻分别为47毫欧和20毫欧，工作频率125KHz，低导通电阻及低开关频率，使得芯片的最高效率可以达到95%，效率曲线如图4所示。

图4：AAP6011A效率曲线

本次客户要求5V/3A的输出能力，以上提供简单的参数设计来作为参考。在实际应用中可以根据调试情况和使用环境做一些微型调整达到使用要求。

【方案】PCR仪精准高效温控系统优选元器件方案

描述- PCR仪一般温度循环为25-90-50-72℃、循环25次以上，早期的PCR仪采用水浴、风扇或压缩机制冷，控温精度较低且调温时间长，导致其无法满足市场上对PCR仪精准、高效的要求。本方案采用II-VI MARLOW公司的高可靠性半导体制冷片、Laird公司的高导热率导热垫片等相关器件，利用半导体制冷片快速温度响应的特点，不仅实现了PCR仪精准、高效的温度控制，而且具有小体积、高可靠性的特点。
