UCC28070A: UCC28070_Design_Tool_2.0问题

Part Number: UCC28070A
Other Parts Discussed in Thread: UCC28070,

用UCC28070_Design_Tool_2.0计算,结果跟旧计算工具差很远,特别是升压电感和电流传感器复位电阻的值:

1、这个值怎么选择?

Enter the Lowest total output power level where CCM is to be maintained  的
PO_CCM(min) = 

2、这值怎么那么大?旧软件算出来只有1K?

  Calculated minimum Reset Resistance (if resistor reset is used) RR (tgt) ≥  128.57
