I'm attempting to power sequence two LTC7151S converters using the Run and Pgood signals. However, even when simulating a single converter, I can't get the Pgood line to cooperate. I have the Pgood pin pulled high with a 10k resistor, however, the signal is kept low even when i'm within 7% of the setpoint. I even opened the test fixture made by lt, and confirmed that the pgood line doesn't work. What is my next step?
