An equation is shown in page19 of the datasheet. I have no idea how this equstion is derived. Please tell me the process of derivation if you know. It's really helpful for me.

Hi York,
Here is additional material on current-mode control for your review:

Hi Tim,
Thanks for your reply. I have read the similar articles you sent me before and know that there is a matter of current-mode control stability and it can be solved by a compensator. I don't really think you get the point that I want to express.
I just want to know how to relate the emulated situation with the actual situation. Why could the emulated ramp waveform represent the actual current waveform in inductance. The datasheet just tells us the result(dI1/dI0=1-1/K) to link the emulated situation to the actual situation directly but does't tell us the procedure. Maybe there are more details that not mentioned in the datasheet, aren't there? I will be grateful if you tell me more about it! Thank you!

Hi York,
Please review the following links for further insight, particularly as it pertains to the emulated current-mode control technique:
