• TPS62050: TPS62050 Output Voltage Rises Unexpectedly

  

  Steve Hendrix

  Part Number: TPS62050 Previous rev of this design, using the TPS62050 to downswitch 6V to 1.8V, works perfectly. Minor rev of the design, no changes in the area of the processor nor the TPS62050. Under some circumstances the output voltage is at 1.8V…

  Part Number: TPS62050 Hi Ti Team ， 1 、 tps62050 的 Cin 电容，也就是 Vin 脚的输入电容规格有特别要求规定吗？是否一定要和规格书中参考设计参数一样，一定要 10uF 下芯片才能更好工作呢？如果更改这个容值参数是否可行，如改为 20uF… 呢？请给些建议？谢谢。 2 、目前客户终端反馈，锂电池给 tps62050 供电，在 Vin 脚输入电容 Cin 在 20uF 时，电池电量会出现下降很快，经测试有 1000uA 的待机电流；但是在 Cin…
