小米10是不是也用的这种大功率超级快充电源芯片方案 KP2201+KP4050？
- 九州同路人回复：不是的，首先需要弄清楚你说的是手机端还是适配器端，手机端小米10用的是电荷泵，效率比这个高。适配器端小米有用这种构架，也有用到必易微电子的快充方案，不过小米使用的快充方案比较多，很多新厂家的方案只要能通过测试，小米都愿意用。手机厂家的快充，18W以上的基本都做了加密处理，就算你知道他用的是哪一家的，拿到同样的硬件，加密软件部分也是搞不定的，除非小米愿意和你合作，给你加密授权！！

必易微电子(KIWI)大功率超级快充电源芯片方案 KP2201+KP4050，苹果20w充电器，2800毫安电池多久能充满？
- 九州同路人回复：手机充电时间取决于手机充电温度控制和充电器功率，比如2800mAh，20W的适配器理论上42mins可以充满。实际上环境温度在10℃左右时，1小时左右可以充满，25℃时需要3小时左右可以充满，30℃时需要5小时以上才可以充满，35℃以上可能充电到80%之后，iPhone手机会一直过温保护，没法充满了

有没有国产可替代TI的LDO芯片供选择，尽可能多的用国产料替代国外物料。提问来源：https://www.sekorm.com/news/45781916.html
- g1225jianmin_世强回复：推荐圣邦微电子的物料，很多产品与其pin to pin兼容，性能上也有一定优势，请参考https://www.sekorm.com/doc/2207409.html
