笔记本移动电源盒的方案?

Other Parts Discussed in Thread: UCC28600, UCC28610, BQ24610

最近在做新的笔记本移动电源盒的方案?要求书出19v 4a

;5v 1a ;12v、1a的输出。支持四节串联的锂电池充电管理芯片。最好能支持太阳能充电!!!请专家指点一下方案的设计要点和芯片的选型!!!

  • 对于线电压的输出可以用UCC28610或是UCC28600设计常规的Flyback来做,如果是采用三副边结构的话,要注意反馈回路轻载时另两路输出过压的问题,可用假负载等方法解决。

    对于四节的锂电池充电,可以采用BQ24610来设计。
