Now we have found a problem in TPS65283, there will be a backchannel after the power is started, it is suspected that the soft start time is too short; We want the output power to be stable, not to go up and then go down and then go up. The following is TPS65283 peripheral circuit and oscilloscope display;
The TPS65283, TPS65283-1 output voltage ramps up at the internal slow-start time of 2.4 ms.
