Self resonant frequency of Output capacitor vs cross over frequency

Prodigy 70 points

HI all

About the relationship between the self-resonant frequency of the output capacitor and the crossover frequency of power supply  IC (DC/DC Converter).

If the output capacitor has a high capacity of about 220uF,the self-resonant frequency (SRF) will be about 300kHz.

If the switching frequency (Fsw) of the power supply IC is 2.0MHz, the self-resonant frequency of the capacitor will be equal to or lower than the crossover frequency (500kHz at 1/5).

Is there a problem with the characteristics of the power supply IC in this state? , What are the risks?

Thanks

Kotaro Suzuki
