Now our custoer use TPS2411 for their product, they use three tps2411 for there designe, Now there has a problem is about the GATE control as bellow:
Question (1) : why three Oring TPS2411 controller’s driving voltage will suddenly fall from the stability, for different loading ways, with different Lower order.
Question (2) : why these three Oring TPS2411 controller’s driving voltage falling into a triangle wave oscillation and will eventually recover?
Question (3) : why gate1 driving voltage oscillation amplitude and oscillation frequency is different from gate2 & gate3?
Question (3) : why Oring TPS2411 controller A point voltage is greater than the C point voltage 10 mv, satisfy the Oring open condition of the controller, but Oring controller driver is not fully open, and the triangular wave oscillation?6283.Oring-TPS2411PW driving abnormal.rar
