Hi Roy,

The Cin cap integrated in package is for reduce SW rising edge ringing which has more noise energy in 30M--300MHz range, LMQ61460 should has same or slight better EMI over LM61460 at freq>300MHz range.

Hi Roy,

You can refer to the white paper to see the CISPR 25 Class EMI results between LMQ61460-Q1 and LM61460-Q1 Figure 29 to highlight the impact of integrated high frequency capacitor. https://www.ti.com/lit/ml/slup408/slup408.pdf#page=11
