I am using the ADN8831 with a switching frequency of 1MHz, and an output current of around 600mA. I am finding that I get around 26mV of ripple on the output. This seems to be having an effect on the output of an image sensor that I am using. Is there a way to reduce this ripple, or would this be typical of this part? I found a Maxim part where they quote an output ripple of around 2mV. Would this be achievable with this part?
