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?
Please update your LTspice model PGOOD should now be working.
