Hi,

My customer wants to know the UCC28056+UCC28600 solution.

Can this solution meet Doe Level VI & CoC5 Tier2. 89% at least and hold up tine >30mS?

Thanks and awaiting the feedback.

Hi Rock,

May I ask what the power level of customer's application, such as output voltage and current. basically , UCC28056 + UCC28600 can meet DOE and CoC requirement if power stage properly designed, since both of them have optimized the control strategy at middle and light load. For hold up time , it majorly decided by the capacitance of bulk caps , and minor impacted by transformer design. large bulk capacitance can hold on long time output .

Thanks.
