Output Ringing Problem in InnoSwitch3-CE dual output Design

Posted by: vivek.gajera on Thu, 07/15/2021

Hi Team, 

We have designed as per power integration simulation tools. 

Our design has two outputs 12V 2A and 5V 3A.  

I have attached the simulation report and we have made PCB and circuit as per that. 

But we are not getting proper output. I have attached the waveform for the same. 

Regards,

Vivek Gajera

We have tune snubber,alos output capacitor, and LC network on output side but we can not resolve it.

Hi Vivek,

I am not seeing any attachment. Can you also provide the schematic diagram and layout if possible?
