Hola,
As subject, below is our schematic and the current design is TPS53624 from 12V to 1V with single phase, transfers output voltage is 1.00625V(without ROV).
Below figure is +1V normal waveform and we can see that the DRVH、DRVL and LL are all switching normally with small ripple(48mV).
And below figure we can see that it has a bigger ripple(70mV) at +1V in front of waveform.
If we zoom in the waveform as below figure and will see the DRVL open twice in transient time and I think that is causing the big ripple's root cause.
May I know that:
1. What reason causes the DRVL will open twice in transient time?
2. Our schematic has any error design?
Brs
