David,I looked over the schematic you sent and it looks like the EAO and ADJ pin connections are swapped compared to Fig. 4 (HV App.) in the Data Sheet. This could be causing the problems you are seeing.

Is there any solution to avoid this wobbling as it is too high in my case. I needed 3.3V as output constant max 3.5V constant. But this fluctuation is driving me crazy. My input varies from 2.5V - 9V...

How can i possibly avoid the ripples which fluctuate very high for input voltage ranging from 3.0V to 4.0V. it is normal after 5V and above. My output voltage should be 3.3V with 1A max. Is there any...

Thanks for information. With the new setup of the compensation my circuit is more stable. Only in a small range of input voltage (abt18 to 22V input) we have some switching frequency jitter.I hope with...

Hi Damien,Thank you for sending this. I initially do not see anything wrong with the schematic. For the waveforms, can we look at WDI, VDD, and RESET signals in the same graph for the NOK condition....
View ArticleForum Post: RE: LM25118MH Stability and High Output Ripple
The unstable problem is solved by decreasing the Cramp from 470pF to 270pF.The output ripple is reduced to 200mV when Vin is 8V. I think that it can be further reduced by adjusting the LC.Thank you for...

Who is the local FAE for this? and what are the production volumes? I notice that this thread is approaching "epic" length. Perhaps if the volumes justify it we can just provide a turn key design.
