I have Rt = 162k, and I measure my switching frequency to be approx 714kHz, so I am in the neighborhood. My PDIM function is performing nominally, 1200us ON every 120Hz. Rsense set to 150mOhms to get LED current = 2A.
Why does my COMP pin measure 1V? The datasheet says it should read 0.7V, but that is not the case. What does it mean if the COMP pin measures 1V?
