Hello,
I'm implementing the LTM4622A with a combined 7V output and 2.2 MHz switching frequency.
To further reduce some expected high-frequency switching noise, what is the recommended approach for attenuation to < 1 mVpp, while also preserving the crossover stability of the supply?
- Are various small capacitor values, in addition to 100uF bulk output capacitance, sufficient?
- Or, can a second-stage LC be employed targeting some frequency below 2.2 MHz?
Thank you.
