My customer shorts Rsense resistor for some reason. It looks the device works normally.
But, I don't understand why the device can work correctly in this case. The inductor current sense voltage is used for the feedback control because this IC is controlled by the peak current mode control, right? The IC integrated the slope compensation. It is only for the compensation for avoiding the sub-harmonic oscillation. I believe if there is only the slope compensation without the current sense voltage, the feedback control is not stable.
What is the risk in the case that Rsense is shorted?
I didn't get why they wants to short Rsense. I will get that information. But, in advance could you give me the advice the risk of Rsense is shorted.
