Hi team
According to the http://www.ti.com/lit/an/snva856/snva856.pdf document ,it mentioned that :" CIO can help with load transients by providing a path from input to output for the load current transient. Remember that the CIO bank will see a voltage of VIN + |VOUT| , and must have a voltage rating in excess of this voltage to help mitigate the voltage derating effect of the ceramic capacitors.".
But I don't quite understand how the CIO can solve the issue caused by load transients, or how does CIO work when the issue caused by load transients happen,or What negative result could happen without the CIO. Could you please explain more specifically to me about these questions?
